Title: Character feature extracting device and method
Inventor: RYU TSUGUAKI
IPC: G06K9/46
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To extract a character feature quantity having only a small storage capacity of the feature quantity and is capable of reflecting on what line are outline points positioned. SOLUTION: An outline point extraction part 11 extracts character pixels (outline points), when background pixels are changed into character pixels (from 1 to 3). An extraction range control part 12 sets pixels in the extraction range of M1×M2 for extracting the features from the outline points extracted by the outline point extraction part 11. A contour extraction part 17 extracts the contour of four-connection or eight- connection input image or a contour, having four-connection and eight-connection mixed together. A contour point direction value calculation part 13 finds a contour point direction value of contour points in the extraction range.  For the contour point direction value, and adjacent contour points positioned in the respective eight- connection direction of all the contour points in the extraction range and found, and the total of the adjacent contour points in the respective directions are set to the elements. An outline point feature extracting part 14 extracts the feature quantity of outline points, using the contour point direction value found in the contour point direction value calculation part 13. A feature contraction part 15 performs contraction processing by taking the average value for each section.

Title: Method and system for assembling frame
Inventor: DEKEYSER MIEK
IPC: H04L12/70
Filed: 2001-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for assembling multi-frame frames. SOLUTION: A value of an identifier (c) inserted in each frame is calculated and the value is transmitted at a rate of a transmitter clock CLKTX. The quantity (m) of an identification value able to be included by the identifier is calculated, so as to be less than a quantity (f) of the frame of the multi-frame. A receiver extracts this identifier from the frame and using it decides a memory position (x) in a temporary buffer CM, so that the amount of frames depending on the memory position (x) is smeller than the amount (f) of the frames in the multi-frame. Then the frames from the memory position of the temporary buffer are read and stored in a succeeding position in a multi-frame buffer memory, independently of the value of the identifier (c). Thus, a clock CLKRX of the receiver is synchronized with the clock CLTKX of a transmitter, in order to attain this processing.
