METHOD AND SYSTEM FOR ANALYZING FACE RECOGNITION FAILURE BY USING IMAGE ANALYSIS

摘要

A face recognition result analysis system of an image recognition robot and a method thereof are provided automatically to analyze a failure cause and inform the cause to a user when a face recognition failure of an image recognition robot occurs. A feature vector extraction unit(100) extracts a feature vector necessary for the discrimination of face recognition by using the motion information of an image obtained through an image recognition robot. A differential binary image conversion unit(102) finds out a differential image of two continued images, that is to say, differential value between two pixels of two images. A connection component analysis unit(104) carries out connected component analysis as to the binary image converted in the differential binary image conversion unit to detect a region which is changed spatially. A user region detection unit merges regions, which are adjacent to each other, among the regions detected in a connection component analyzer. A feature vector calculation unit(108) calculates feature amount vectors based on the user regions merged in the user region detection unit.
