Image sequence coding method for use in video compression field, involves selecting images with additional condition, for high frequency images, and calibrating selected images by performing inverse operation of images scaling step

摘要

The method involves selecting images, among low or high frequency images, obtained by an intra-coding of an image at lower decomposition level or by temporal filtering between an image of a pair of images and another image succeeding the pair of images, with additional condition for the high frequency images. The selected images are calibrated by performing an inverse operation of images scaling step. Independent claims are also included for the following: (A) a method of decoding a sequence of images (B) an encoder (C) a decoder.
