Abstract
The invention relates to a method intended to automatically create a description of a video sequence—i.e. its table of contents—by analyzing the video sequence. First is a temporal segmentation of the video shots of the sequence, using camera motion parameters. This segmentation uses a similarity criterion involving, for sub-entities of each shot, the level of homogeneity of these sub-entities on the motion parameters of the camera used to acquire the original images and generate the bitstream constituting the processed sequence.
