Abstract:
A method and apparatus for coding a block of video data using index or pixel value prediction including a copy-by-pattern-search mode are disclosed. According to the present invention, a current search pattern is determined based on one or more previous coded pixels. One or more predictors are derived according to the current search pattern for a current index or pixel value of a current pixel in the current block. Encoding or decoding is then applied to one or more following indices or pixel values of one or more following pixels including the current pixel using the predictors. In a simplest case, the one or more previous coded pixels correspond to a single previous coded pixel at the left side of the current pixel and the one or more following pixels contain only the current pixel.
