Brief description of the segmentation of the field of movement of an image and its application to the encoding of video images

摘要

The segmentation process of the field of movement of the invention is to form a field of motion by blocks from motion vectors assigned to the image pixels, and then to carry out a treatment of the field of vectors by blocks in order to extract of this field, a set of motion vectors dominant, by removal of the vectors, in order to preserve as representatives of classes of movement between the widened, a vector of this reduced set of dominant vectors is then d - assigned to each block, and the resulting field, after temporal filtering is used for the coding of the image by a coding tree "quad -." / p & & p & the invention applies, in particular, to the construction of digital data for assisting the decoding in the limit of 1 mbit / s / p
