METHODS FOR DECODING VIDEO SIGNALS, ELECTRONIC DEVICES, STORAGE MEDIA, BIT STREAM STORAGE METHODS, AND BIT STREAM TRANSMISSION METHODS

Abstract

The invention relates to a method for decoding video signals, electronic devices, and computer-readable storage media. This method comprises the following steps: receiving, from a video signal, a picture frame consisting of a first component and a second component; determining a classifier for the first component based on the first set of one or more samples of the second component associated with the corresponding sample of the first component and the second set of one or more samples of the first component associated with the corresponding sample of the first component; determining the color deviation with respect to the corresponding sample of the first component according to the classifier; and changing the value of the corresponding sample of the first component based on the determined sample deviation. In some schemes, the first component is the luminance component and the second is the chrominance component, and the classifier is determined by a combination of a band deviation classifier and a edge deviation classifier.
