SPECIFIC SCENE EXTRACTION METHOD BY COMPREHENSIVE DETERMINATION SYSTEM USING MAHALANOBIS DISTANCE, AND DEVICE THEREOF

PROBLEM TO BE SOLVED: To provide an analogous moving image extraction device with the increased recall ratio and relevance ratio. SOLUTION: If Mahalanobis distance D2is determined as complying with the condition of D2≤Dt2in j or more frames of the successive k frames, the frame Fnto be determined is determined as belonging to the scene analogous to the standard scene, or/and if the number of frames belonging to the scene analogous to the standard scene of a plurality of frames between scene changes is determined as exceeding R%, the assembly of the moving image frames is adopted as a specific scene analogous to the standard scene.
