In the system of Fig. 1 a participant 10 is shown at an event, such as a wedding, and is being photographed by a photographer 12 holding a camera 14. Camera 14 may be any known conventional or digital camera capable of taking photographs. Participant 10 preferably wears an identification tag 16 having a discernible pattern. Alternatively, tag 16 may be a printed or otherwise integrated design on an outer garment 18 of participant 10. Photographic image 22 is preferably scanned and electronically provided to identification apparatus 20, or electronically provided by camera 14 where camera 14 is a digital camera. Identification apparatus 20 preferably employs techniques well known in the art for locating identification tag 16 within a photographic image 22 and comparing identification tag 16 with an event/participant database 24 in order to identify the intended recipient of the photographic image 22 such as participant 10. Database 24 typically comprises at least one preprogrammed record 25 including an image of identification tag 16 or any known representation of tag 16 that may be used in locating tag 16 in image 22 using methods known in the art. Record 25 also preferably includes address information regarding the intended recipient or recipients of images in which identification tag 16 has been located. The address information may include electronic mail addresses, postal addresses, and any other well known addressing information. Record 25 may also include an identifier identifying participant 10 as a participant in one or more events. Additionally or alternatively, the pattern on tag 16 may include identity and/or address information of participant 10 using encoding techniques known in the art such as a bar code. This information need not be stored in database 24 as identification apparatus 20 may decode it using decoding techniques known in the art. Image delivery apparatus 26 is also preferably provided for delivering photographic image 22 to the address or addresses indicated in database 24 for identification tag 16. Delivery methods may include postal service such as is shown at 30, electronic mail via a network 34, such as the Internet, as is shown at 32, or any other known delivery means. Either of identification apparatus 20 and image delivery apparatus 26 is preferably capably of removing identification tag 16 from photographic image 22 using known image editing techniques, such as is shown by a photograph 28 received by recipient 10 in which tag 16 has been removed. Reference is now made to Fig. 3 which is a simplified pictorial flow illustration of a method of providing identification tag 16 to participant 10 operative in accordance with a preferred embodiment of the present invention. A server 36 is provided with database 24. In one embodiment, server 36 sends an invitation 42 electronically to a computer terminal 38 of participant 10 via network 34 together with a printable image of identification tag 16 or other known file format or software which may be used to print tag 16 at a printer 40, typically on adhesive paper which may be worn. In another embodiment, server 36 prints out tag 16 at a printer 44 or tag 16 is otherwise manufactured, typically on adhesive paper which may be worn. A printed invitation 46 is then sent together with tag 16 to participant 10 via regular mail as is shown at 48. In another embodiment, participant 10 provides identification and/or address information to server 36, such as via HTML forms at a World Wide Web site maintained by server 36 and accessible to participant 10. Tag 16 is then selected and sent to participant 10, and the information received from participant 10 is either stored in database 24 together with the associated tag information or encoded into tag 16 as described above, or both. Fig. 4 is a simplified pictorial illustration of another method of providing identification tag 16 to participant 10 operative in accordance with a preferred embodiment of the present invention. A computer terminal 50 is provided with database 24, typically at the entrance of a banquet hall. Participant 10 enters his address information which is then stored in database 24 together with information regarding a tag, such as tag 16, selected from a pool of unused tags or otherwise uniquely generated for the participant and the event. Terminal 50 then prints tag 16 at a printer 52 such as on adhesive paper which may be worn. Reference is now made to Figs. 5 and 6 which, taken together, are simplified pictorial flow illustrations of a gift fulfillment system constructed and operative in accordance with a preferred embodiment of the present invention, and Fig. 7 which is a simplified flowchart illustration of a preferred mode of operation of the system of Figs. 5 and 6. As in Fig. 3, server 36 is provided with database 24, and additionally with a gift database 54. Gift database 54 typically includes preconfigured gift lists for one or more events, such as lists of wedding gifts for brides and grooms. Server 36 typically sends a gift list 56 electronically to computer terminal 38 of participant 10 via network 34. Gift list 56 preferably indicates the gifts that have not yet been chosen and may be sent in HTML or any other known format. An invitation 58 is preferably sent to participant 10 providing both a user identification and an event identification. Participant 10 selects one or more gifts and sends a gift purchase request to server 36, preferably including appropriate user identification and event identification and payment or billing information. Gift database 54 is updated to reflect the gift purchase request. Fig. 6 shows server 36 providing a thank you note to participant 10 based on the his gift purchase recorded in gift database 54 and using address information from database 24. In one embodiment, server 36 sends a thank you message 60 electronically to computer terminal 38 of participant 10 via network 34. In another embodiment, server 36 prints out a thank you note 62 at printer 44 which may then be sent to participant 10 via regular mail as is shown at 64. Fig. 8 is a simplified pictorial illustration of a method of identifying participant 10 of Fig. 1 to be used in place of or in addition to employing identification tag 16 as described hereinabove with reference to Figs. 1 - 4, and operative in accordance with a preferred embodiment of the present invention. Computer terminal 50 is provided with database 24, typically at the entrance of a banquet hall. Participant 10's face is scanned at a scanner 66 and encoded using any known face scanning and encoding system. Participant 10 also enters his address information which is then stored in database 24 together with his encoded face information. Identification of participant 10 may be performed as described in Figs. 1 - 2 with the exception that participant 10 is identified using the encoded face information stored in database 24. Reference is now made to Fig. 9 which is a simplified pictorial flow illustration of an image identification and delivery system constructed and operative in accordance with another preferred embodiment of the present invention. In the system of Fig. 9 a camera 68 is typically provided in a fixed location, such as along a boardwalk in an amusement park. An amusement park goer 70 is preferably provided with a smart card 72 onto which information is stored identifying park goer 70, such as his address. Smart card 72 may be any known smart card or tag capable of sending transmissions. Card 72 may additionally be capable of receiving transmissions. A communications unit 74 is also provided for communicating with card 72 and controlling camera 68. A computer 76 is also provided for communicating with unit 74. Typical operation of the system of Fig. 9 is now described. In one embodiment, card 72 periodically transmits a signal that, when park goer 70 comes within a predetermined range from camera 68, is received by unit 72 which then triggers camera 68 to photograph park goer 70. The signal may include information identifying park goer 70, or, upon receiving the signal from card 72, unit 74 may transmit a signal requesting identification information which card 72 then transmits to unit 74. In another embodiment camera 68 is set to photograph periodically. As camera 68 takes a photograph, unit 74 transmits a signal requesting identification information from any smart card within the camera's range and card 72, being within range, responds by transmitting park goer 70's identification information. Computer 76 preferably stores the photograph taken by camera 68 together with the identification information received from card 72 and stores the information in a database 78. The photographs may be automatically delivered to park goer 70 in the same manner as described hereinabove with reference to Figs. 1 - 2, or delivered after selection and payment at an electronic kiosk 80 designated for this purpose. It is appreciated that the steps described with reference to Figs. 2 and 7 need not necessarily be performed in the order shown unless otherwise indicated, and that in fact different implementations of the steps may be employed to yield similar overall results. Reference is now made to Fig. 10, which is a simplified pictorial flow illustration of an image identification and delivery system constructed and operative in accordance with another preferred embodiment of the present invention and Fig. 11 which is a simplified flowchart illustration of a preferred mode of operation of the system of Fig. 10. In the system of Fig. 10, one or more participants 110 are shown being photographed at an event, such as a reception, by a photographer 112 holding a camera 114. Camera 114 may be any known film or electronic camera capable of taking photographs, such as video photographs or still photographs. Each participant 110 preferably wears an identifier tag 116. The identifier tag 116 may be in any suitable form, such as a badge, a pin, a sticker or a necklace or alternatively may be integrated with a worn garment. In accordance with a preferred embodiment of the present invention, the identifier tag 116 preferably comprises a color and pattern coded tag, having coding in at least two dimensions, such as color and position. Alternatively, the identifier tag 116 may be coded in a greater or lesser number of dimensions, such as only color. It is important, however, that the identifier tag 116 be readily detectable to a degree allowing for straightforward decoding thereof by automatic scanning apparatus, wherein variations in camera angles and lighting do not generally defeat successful detection. A preferred form of identifier tag 116 is a generally circular tag, as shown, having a circular central region 118 surrounded by variously colored segments 120, the coding of which readily identifies the wearer and corresponds to an alphanumeric identification code 122, which is preferably printed on the tag 116. Identification code 122 may be printed on the back of the tag 116 or alternatively at any appropriate location on the front thereof, such as in the central region 118 or in one or more of colored segments 120. It is appreciated that the color coded identifier tag described hereinabove and shown in Fig. 10 is much more readily detectable and decodable than would be a conventionally bar-coded tag of similar size. A photographic image 123 taken of participants 110 by camera 114 is provided in electronic form to identification apparatus 124 either directly from a digital camera or via a scanner (not shown), when a film camera is employed. Identification apparatus 124 preferably employs techniques well known in the art for locating identifier tag 116 within the photographic image 123, decoding the tag and associating each photographic image 123 with the alphanumeric identification code 122 corresponding to each person appearing in the photographic image. Identification apparatus 124 preferably downloads both the images and the alphanumeric identification code or codes associated with each image to a database 125. Database 125 typically comprises a pre-programmed randomly accessible record of each image keyed to the alphanumeric identification code associated with the identifier tag worn by each person appearing in each image. In accordance with a preferred embodiment of the present invention, following the event, once the identification apparatus 124 has downloaded the data corresponding to the images and the alphanumeric identification code or codes associated with each image to the database 125, any participant who wishes to view or obtain photographs in which he appears can access them electronically and print them out. This can be done, in accordance with one embodiment of the present invention, by the participant using a computer 130, a printer 132 and a computer network 134, such as the Internet, entering a web site which provides access to database 125. Alternatively, the participant can send an e-mail message to a server which provides access to database 125. Should the participant wish to receive the images electronically, he may enter or e-mail his alphanumeric code 122, and his e-mail address together with a request for all images associated with his identifier tag alphanumeric identification code 122. Should the participant wish to receive a hard copy, he may communicate in any suitable manner with image delivery apparatus 136 and provide a mailing address for delivery of a hard copy 128 of one or more images 123. It is appreciated that conventional transaction software may be associated with database 125 and/or with image delivery apparatus 136 to enable payment to be obtained, if desired, for either or both of the virtual or hard-copy images. Reference is now made to Fig. 12, which is a simplified flowchart illustration of a preferred method of detection and decoding of an identifier tag 116 of the present invention. As seen in Fig. 12, the identification apparatus, which is typically embodied in a conventional computer such as a PC, detects the presence and location of an identifier tag 116 in an image 123. Preferably both the identifier tag 116 and the image 123 are in color. An image of the identifier tag 116 is then extracted from the remainder of the image 123 and the identifier tag 116 is decoded. Reference is now made to Fig 13 which illustrates a preferred method of detection of an identifier tag in accordance with a preferred embodiment of the present invention It is seen at the outset that the method of Fig 13 employs two independent detection techniques in parallel One of the techniques is a pattern recognition technique which converts the color image 123 (Fig 10) to a grey scale and performs edge detection thereon Subsequent to edge detection, the detected edges are correlated with predetermined shapes, typically a circular shape corresponding to the overall configuration of the identifier tag 116 The other technique is a color detection technique which converts the color image 123 (Fig 10) from RGB to another color base, such as HSV, and performs segmentation of the image according to color and intensity thresholds Following segmentation, searching is carried out for a known color or colors of one or more regions of identifier tag 116 The known color may be white or any other suitable color The results of both detection techniques are ANDed together to provide a relatively robust indication of the presence and location of one or more suspected identifier tag 116 in an image 123 For each suspected identifier tag 116, spatial coordinates of the center thereof are determined One or more identifier tag parameters are then checked One such parameter may be the relative circumferences of the outer diameter of the suspected tags 116 as well as the outer diameter of the central region 118 thereof Another such parameter may be a check that all colors appearing in segments 120 (Fig 10) are within a set of predetermined colors Reference is now made to Fig 14 which illustrates a preferred technique for decoding an identifier tag 116 The method of Fig 14 preferably comprises RGB color enhancement of the extracted image of identifier tag 116, followed by conversion from RGB to another color base, such as HSV, segmentation of the image of extracted image according to color and intensity thresholds and searching for known colors of all of segments 120 Once each segment is associated with a known color, a sequence of colors is detected circumferentially of the identifier tag 116, preferably at multiple radii Once the color sequence has been determined with sufficient certainty, it is applied to a look up table to provide the alphanumeric code 122 (Fig 10) Reference is now made to Fig. 15, which is a simplified pictorial flow illustration of an image identification and delivery system constructed and operative in accordance with another preferred embodiment of the present invention and Fig. 16 which is a simplified flowchart illustration of a preferred mode of operation of the system of Fig. 15. In the system of Fig. 15, one or more participants 210 are shown being photographed at an event, such as a reception, by a photographer 212 holding a camera 214. Camera 214 may be any known film or electronic camera capable of taking photographs, such as video photographs or still photographs. In contrast to the embodiment of Fig. 10, each participant 210 need not wear an identifier tag. In accordance with the present invention, the individual participants are recognized by using known and conventional face recognition techniques. Descriptions of some known techniques appear in the following U.S. Patents, the disclosure of which is hereby incorporated by reference: 4,975,969; 5,012,522; 5,164,992; 5,410,609; 5,430,809; 5,432,864; 5,524,065; 5,642,431; 5,644,765; 5,715,325; 5,729,619; 5,787,186; 5,801,763; 5,802,208; 5,805,720; 5,835,616; 5,850,470; 5,852,669.

Camera 302 is preferably discretely located so that it is not normally seen. The identification subsystem 304, which may operate much in the same manner as the identification apparatus 124 in the embodiment of Fig. 10, provides identification outputs to one or both of an audio annunciator 306, such as an earpiece, and a visual annunciator 308, such as a "head-up display" 310 associated with the user's eyeglasses 312. The identification outputs may provide the name of an identified person, as well as other relevant particulars of that person. In the illustrated embodiment, the "identified" person wears an identifier tag 316, which may be similar in all relevant respects to identifier tag 116. The information on the identifier tag 116 is employed by the identification subsystem 304 to identify the person, whose tag is viewed by camera 302. For this purpose the identification subsystem 304 preferably employs a database 325, which may be similar in all relevant respects to database 125 in the embodiment of Fig. 10. Turning now to the embodiment of Fig. 17B, there is shown an instantaneous personal identifier system which does not require the use of an identifier tag 116. This system operates based on face recognition, such as described in any of the above-listed U.S. Patents. In the illustrated embodiment, a user, designated by reference numeral 400, carries an instantaneous personal identifier assembly, comprising a camera 402 which provides inputs to an identification subsystem 404. Camera 402 is preferably discretely located so that it is not normally seen. The identification subsystem 404, which may operate much in the same manner as the identification apparatus 224 in the embodiment of Fig. 15, provides identification outputs to one or both of an audio annunciator 406, such as an earpiece, and a visual annunciator 408, such as a "head-up display" 410 associated with the user's eyeglasses 412. The identification outputs may provide the name of an identified person, as well as other relevant particulars of that person. In the illustrated embodiment, the "identified" person need not wear an identifier tag, but is recognized by his facial features, which are stored in a database 425, which may be similar in all relevant respects to database 225 in the embodiment of Fig. 15. Reference is now made to Fig. 18 which illustrates another embodiment of the present invention. In the system of Fig. 18, one or more participants 110 are shown being photographed at an event, such as a reception, by a photographer 112 holding a camera 114. Camera 114 may be any known film or electronic camera capable of taking photographs, such as video photographs or still photographs. Each participant 110 preferably wears an identifier tag 116. The identifier tag 116 may be in any suitable form, such as a badge, a pin, a sticker or a necklace or alternatively may be integrated with a worn garment. In accordance with a preferred embodiment of the present invention, the identifier tag preferably comprises a color and pattern coded tag, having coding in at least two dimensions, such as color and position. Alternatively, the identifier tag may be coded in a greater or lesser number of dimensions, such as only color. It is important, however, that the identifier tag be readily detectable to a degree allowing for straightforward decoding thereof by automatic scanning apparatus, wherein variations in camera angles and lighting do not generally defeat successful detection. A preferred form of identifier tag 116 is a generally circular tag, as shown, having a circular central region 118 surrounded by variously colored segments 120, the coding of which readily identifies the wearer and corresponds to an numeric identification code 122, which is preferably printed on the tag 116. Identification code 122 may be printed on the back of the tag 116 or alternatively at any appropriate location on the front thereof, such as in the central region 118 or in one or more of colored segments 120. It is appreciated that the color coded identifier tag described hereinabove and shown in Fig. 1 is much more readily detectable and decodable than would be a conventionally bar-coded tag of similar size. A photographic image 123 taken of participants 110 by camera 114 is provided in electronic form to identification apparatus 124 either directly from a digital camera or via a scanner (not shown), when a film camera is employed. Identification apparatus 124 preferably employs techniques well known in the art for locating identifier tag 116 within the photographic image 123, decoding the tag and associating each photographic image 123 with the numeric identification code 122 corresponding to each person appearing in the photographic image. Identification apparatus 124 preferably downloads both the images and the alphanumeric identification code or codes associated with each image to a database 125. Database 125 typically comprises a pre-programmed randomly accessible record of each image keyed to the alphanumeric identification code associated with the identifier tag worn by each person appearing in each image. In accordance with a preferred embodiment of the present invention, following the event, once the identification apparatus 124 has downloaded the data corresponding to the images and the alphanumeric identification code or codes associated with each image to the database 125, any participant who wishes to obtain photographs in which he appears can dial a certain phone number and using the telephone key pad to enter his code. This can be done, in accordance with one embodiment of the present invention, by the participant using a telephone 130 and a telecommunication network 134, calling a certain telephone number and entering the access code to database 125. The Image Delivery Apparatus 136 may detect the caller's phone number and using telephone directory database 137 to obtain the caller address. It is appreciated that conventional transaction software may be associated with database 125 and/or with image delivery apparatus 136 to enable payment to be obtained, if desired, for either or both of the virtual or hard-copy images. The payment method can be using the caller's phone bill or any suitable manner. An example of a tag is now described. Preferred badge definition: An example of a suitable badge is shown in Fig. 19. It typically comprises two parts. The first part corresponds to a "Text Area" where written information can appear. The second part corresponds to the "Color-coded identifiers" area. It may comprise a centered "Flower" and an additional "Inclination segment". The "Flower" may comprise six color segments numbered in Fig. 19 from #1 to #6. The "Inclination segment" has the number #7. Preferred "Color-coded identifiers" features: The "Color-coded identifiers" may have the following properties, in the illustrated embodiment: The badge may be printed on non-glossy white paper. The internal circle of the "Flower" may be white and surrounded by a lmm width black line. The internal circle diameter of the "Flower" may equal 10mm. The outer diameter of the "Flower" typically equals 30mm. The outer perimeter color of the "Flower" may be a black line of lmm width. The badge may be printed on a white paper with an outer margin of 7mm from the perimeter of the "Flower". The segment colors may be one of the example valid colors described in the table of Fig. 20. Two consequent segments typically do not have the same color. The "Inclination segment" is typically tangent to the segment #5 as shown in Fig. 19. In the illustrated embodiment, the diameter of segment #1 equals 10mm. Segment #7 is also surrounded by a lmm width black line. The color of segment #1 may be one of the valid colors and has to be different from the color of segment #5. Typical camera type and settings may be as follows: Camera type : Nikon coolpix 900 digital camera Picture quality : High Suitable photographic conditions may be as follows: Field of view : between 70cm to 150cm. The photographs are typically taken with a flash. The distance of the object is typically approximately 2 meters. An authorized code is composed of 9 digits. The first three digits are constant digits (i.e., 898 ). The following 6 digits are the decoded numbers corresponding to the numbered segments (from #1 to #6) as described in Fig. 20.
