VIDEO CODING METHOD OF EXPLOITING THE TEMPORAL REDUNDANCY BETWEEN SUCCESSIVE FRAMES

摘要

The invention relates to a video coding method of exploiting the temporal redundancy between successive frames in a video sequence. A reference frame, called I-frame, is first approximated by a collection of geometric features, called atoms. The following predicted frames called, P-frames, are approximated by the geometric transformations of the geometric features (atoms) describing the previous frame. Preferably, the I-frame is approximated by a linear combination of N atoms $selected\; in\; a\; redundant,\; structured\; library.\; They\; are\; indexed\; by\; a\; string\; of\; parameters\; gamma\; n\; representing\; the\; geometric\; transformations\; applied\; to\; the\; generating\; mother\; function\; g(x,y)\; and\; the\; cn\; are\; weighting\; coefficients.$
