The device which detects the cutting point of the dynamic picture image on the basis of the prediction error of the feature quantity

摘要

The device which detects the cutting point of the dynamic picture image includes the frame feature quantitative extraction section (21) with the estimate section (22) with the prediction error calculation section (23) with the cutting point decision section (24). The estimate section (22), it was extracted predicted value of the feature quantity of each frame after the present frame which includes the present frame which is the frame of the present decision object, the frame feature quantitative extraction section (21) by, it calculates making use of the feature quantity of the frame of past predetermined number than the present frame. The prediction error calculation section (23), after the present frame which was calculated the feature quantity and the estimate section of each frame after the present frame (22) by, comparing with the predicted value of the feature quantity of the frame which corresponds, it calculates the prediction error that the feature quantity and predicted value. The cutting point decision section (24), it decides whether or not each prediction error which was calculated the prediction error calculation section (23) by satisfies specified criterion, each each prediction error assuming that when criterion is satisfied, the present frame is the cutting point outputs the frame number.
