AI Technical Summary

⚠Technical Problem

The poor image prediction performance in existing technologies is mainly due to the fact that inter-frame prediction mode, intra-frame prediction mode, or intra-frame template matching mode only bases the prediction block on the reference block when generating the prediction block, resulting in poor prediction performance.

⚗Method used

By determining the first prediction block of the target image block and obtaining offset compensation information based on the first template and the second template, the second prediction block of the target image block is determined by using the reconstructed pixels in the adjacent pixel region of the target image block included in the first template and the reconstructed or predicted pixels in the adjacent pixel region of the reference block included in the second template.

🎯Benefits of technology

It improves image prediction performance, increases the accuracy and precision of prediction blocks, and makes predicted pixels closer to the original pixels.
