METHOD AND DEVICE FOR CLASSIFYING PIXEL OF VIDEO IMAGE

摘要

Disclosed are a method and device for classifying a pixel of a video image. An embodiment of the method comprises: acquiring a directional value corresponding to any pixel or pixel block in the video image; acquiring a complexity value corresponding to the pixel or pixel block; where the classification number of the directional value is greater than or equal to the classification number of the complexity value; and acquiring a classification result of the pixel on the basis of the directional value and of the complexity value of the pixel. Embodiments of the present invention increase the proportion of a directional characteristic classification in the process of classifying the pixel or pixel block of adaptive filtering, thus improving the rationality of a filter design, and allowing for improved coding efficiency.
