LIMITATION OF ERROR PROPAGATION IN LINE-BASED PREDICTION FOR INTRA CODING

摘要

The present invention relates to encoding and decoding of image and/or video data divided into a plurality of partitions in such a way that a partition is predicted without referring to already reconstructed pixels. The encoding is then performed by coding the difference between the partition and the prediction thereof. Correspondingly, decoder operates by reconstructing the coded partitions by predicting the partition without using already reconstructed/decoded data and by adding the prediction to the received differences. Predicting without reference to previously reconstructed pixels may be achieved by signaling a predetermined value which is then used as a prediction for the partition's pixels.
