Abstract

THE FEATURE POINTS OF THE INPUT VIDEO SIGNAL IS DETECTED BY CANNY EDGE DETECTING METHOD (44), THE COORDINATES OF THE FEATURE POINTS DETECTED WHEN THE FEATURE POINT DETECTED IS CHAIN CODED (45), THE LENGTH OF THE REGION, INCLUDING THE FEATURE POINTS, OF WHICH EDGE INTENSITY IS THE SPECIFIED VALUE OR MORE IN THE EDGE INTENSITY MAXIMUM CHANGE DIRECTION AT THE FEATURE POINT COORDINATES OBTAINED WHEN THE FEATURE POINT IS DETECTED IS CODED (41), AND THE CHAIN-CODED DATA OBTAINED WHEN CHAIN-CODING AND THE REGION LENGTH CODED DATA OBTAINED WHEN THE EDGE REGION LENGTH IS CODED STEP IS MULTIPLEXED (43). THEREBY THE AMOUNT OF BITS REQUIRED FOR CODING OF THE COORDINATES INFORMATION CAN BE REDUCED, AS A RESULT THE TOTAL AMOUNT OF CODES CAN BE REDUCED.(FIG. 3)
