<p>Techniques for improving the accuracy of prediction in intra-frame coding. A prediction mode can specify a pixel along a direction independently of other pixels along the same direction. In an embodiment, an encoder selects a prediction mode to best represent the image block. In an alternative embodiment, a decoder reconstructs each pixel in the image block by weighting neighboring pixels according to a weight matrix specified by the prediction mode.</p> |
