Abstract

An electronic apparatus performs a method of decoding video data. The method comprises: receiving, from the video signal, a picture frame that includes a first component, and a second component; determining a classifier for the first component based on a first set of one or more samples of the second component associated with a respective sample of the first component; determining a sample offset for the respective sample of the first component according to the classifier; and modifying a value of the respective sample of the first component based on the determined sample offset, wherein the first component and the second component are chroma components. The picture frame further includes a third component, and the classifier for the first component is additionally based on a second set of one or more samples of the third component associated with the respective sample of the first component.
