FIELD: information technology.SUBSTANCE: invention relates to methods and devices for internal coding unit having grouped pixels. Prediction of pixels in second group is produced by evaluation of pixels in first group and in second group. Method of encoding block in an image describes steps of: encoding unit in image using internal prediction by pixel separation inside unit, on first group and second group is encoded pixels in first group of adjacent pixels to encoding pixels in second group. At that, prediction for pixels in second group is obtained based on pixels in first group and in second group and adjacent pixels in already encoded blocks.EFFECT: technical result consists in improvement of efficiency of encoding and prediction accuracy is achieved by using device, which includes video encoder for encoding block in image using internal prediction by pixel separation inside the unit, at least on first group and second group and for encoding pixels in first group to encoding pixels in second group.44 cl, 21 dwg |
