MATRIX WEIGHTED INTRA PREDICTION OF VIDEO SIGNALS

Abstract:

The present disclosure provides methods for performing simplified matrix weighted intra prediction. The method can include: determining a classification of a target block; and generating, based on the classification, a matrix-weighted intra prediction (MIP) signal, wherein determining the classification of the target block comprises: in response to the target block having a size of 4.times.4, determining that the target block belongs to a first class; or in response to the target block having a size of 8.times.8, 4.times.N or N.times.4, N being an integer between 8 and 64, determining that the target block belongs to a second class.
