Abstract: A first signal of two signals to be compared for similarity is divided into small areas and one small area is selected for calculating the correlation with a second signal using a correlative method. Then, the quantity of translation, expansion rate and similarity in an area where the similarity, which is the square of the correlation value, reaches its maximum, are found. Values based on the similarity are integrated at a position represented by the quantity of translation and expansion rate. Similar processing is performed with respect to all the small areas, and at a peak where the maximum integral value of the similarity is obtained, its magnitude is compared with a threshold value to evaluate the similarity. The small area voted for that peak can be extracted.

Abstract: For accurate scene-change detection, the amplitudes of sub-band signals subjected to the spectral decomposition are detected, and the detected amplitudes are smoothed and sampled during smoothing. Then, the amount of spectral change is determined based on the smoothed sub-band amplitude and the smoothed sub-band amplitude which is one sampled amplitude before that smoothed sub-band amplitude. It is then determined whether or not the determined amount of spectral change is greater than a predetermined threshold, and processing is performed based on the determination result.
