An algorithm for scene change detection in h.264/avc compressed domain
description In this report, an algorithm is proposed to detect scene changes including both abrupt scene changes and gradual scene changes in H.264/AVC compressed domain with a minimal decoding. The report first focuses on discussing about how to detect abrupt scene changes at P pictures using the number of intra-coded MBs with a local maximum filter to prevent false alarm detection due to fast moving, zooming or panning camera actions. In addition, the report also touches on detecting abrupt scene changes at I pictures by taking advantage of the motion-compensative components of B pictures. It also considers the false detection caused by intra-coded macroblocks imposing on the statistical values used for detection. By introducing a threshold to detect whether the number of intra-coded macroblocks in a particular B picture exceeds the predefined value or not, it is able to prevent the false alarm. Moreover, the report also discusses about the algorithm to detect gradual scene changes in H.264/AVC compressed domain in its second part. By executing two abrupt scene change detection algorithms at the same time, the input used in the gradual scene change is generated. With the assistance of a median filter and other identifier equations, a list of candidates belonging to a gradual scene change is firstly defined. Then with a grouping technique by monitoring the distance between adjacent candidates in the list and the minimum size of each group that it must exceed, a list of gradual scene changes is formed.
