METHOD FOR ENCODING A SEQUENCE OF DIGITIZED IMAGES

摘要

Pixels with associated pixel values form a sequence of digitized images that are encoded by predicting pixels of the images and encoding the prediction errors. At least a part of the pixels are encoded by determining trajectories, each running through a pixel to be encoded and through other previously encoded pixels from the image of the pixel being encoded and/or from one or more images that are temporally proximate to that image. For each of the trajectories determined, a valuation parameter is in inverse proportion to the deviations in the uncoded associated pixel values of the other pixels along a trajectory. A predicted pixel value of the pixel to be encoded is determined based on the other pixels of the trajectory with the highest valuation.
