Abstract: A method of processing a raster scan video signal representing an image and detecting the outline of one or more objects in the image represented by the video signal includes the steps of encoding the raster scan video signal as a sequence of binary pixel values, with each binary pixel value representing one pixel of the image, and then, for each of a plurality of the pixels, performing the following steps: detecting when the binary pixel values representing the pixel and a horizontally adjacent pixel are distinct; and detecting when both (a) the binary pixel values representing the pixel and a vertically adjacent pixel are distinct, and (b) the binary pixel values representing a pixel horizontally adjacent thereto are distinct. The position of the pixel is reported when either of the detecting steps detects distinct binary pixel values. The second detecting step eliminates redundant pixel reporting by eliminating the reporting of double diagonal pixels. 
     Apparatus for carrying out the method includes means (21) for quantizing the video signal, means (22) for detecting vertical edges in the quantized image, means (23) for detecting horizontal edges in the quantized image, and means (24) for eliminating or preventing redundant reports of pixels along the outline of the objects in the image.

A tracking signal for controlling the tracking alignment of the rotary playback head (1A,1B) is generated in response to the level comparison, and is adjusted in level response to the level of the tracking control signal.

Abstract: A fiber optic frequency shifter comprises an optical fiber (200) having an acoustic conducting medium (202) for propagation of an acoustic signal. The acoustic medium is preferably shaped as a rod, and the acoustic signal propagates longitudinally down the rod. The optical fiber is wound around the rod with plural turns such that the axis of the fiber is at an angle relative to the wave fronts of the acoustic signal. As the acoustic signal propagates through the rod, it causes stress on the portions of the fiber in contact with the rod. The stress on the fiber caused by the acoustic wave causes optical energy to be transferred between two propagation modes of the fiber. This transferred energy is shifted in frequency by the frequency of the acoustic signal. By tightly winding the turns of the fiber, high frequency shifts can be obtained.

Abstract: There is disclosed a system for storing an image of an object to be identified and for retrieving the stored image of the object for displaying the same on a display screen. The system includes electronic scanning means for scanning the object on a line-to-line basis to provide a analog signal for each line indicative of the information content of said object. The analog information is converted by a digitizer into pixels which define a matrix which matrix determines the information content for each line. A window area is generated which area encompasses a predetermined area within a larger display area. The window area is used to generate and to respond to a first set of digital information which information is derived from the matrix pixels. This first set of digital information is such that the window area contains a limited number of pixels plus a limited number of lines, each of which is generated when the window area is scanned. A critical identification area is defined by the apparatus which critical identification area is determined by the common characteristics areas associated with the object to be scanned. In an image of a person's face, the area consists of a "T" zone which encompasses the eyes, nose and mouth   area. In this critical identification area, information is generated or employed which employs pixels that were skipped during the scanning of the window area. In this manner the critical identification area contains more detailed information to enable one to thereby authenticate the regenerated image from the first and second sets of digital data to thereby enable one to positively identify one person as compared to another person. The technique thus described provides a video compression of such data whereby the resultant digital information is capable of being stored on a very limited medium such as a magnetic stripe associated with a credit card.
