Methods and devices for predicting decoding, computer storage media, and methods for reading bit streams.

Abstract

The invention relates to a predictive method and apparatus for decoding and patching computer storage media. This method includes the following steps: obtaining nearby reference pixels from at least one edge of the block to be decoded to obtain the first set of nearby reference pixels; identifying the reference point from at least one edge, and determining the positions of the selected reference pixels corresponding to at least one edge according to a predefined number of samples; Based on the positions of the reference pixels to be selected, select reference pixels corresponding to the positions of the reference pixels to be selected from the first set of adjacent reference pixels, and create a subset of adjacent reference pixels from the selected reference pixels; and based on the subset of adjacent reference pixels, perform predictive decoding on the block to be decoded.
