Abstract: Template matching intra prediction based on a given priority is provided. Priority values of all, or a subset of the pixels on a border between a current block and a reconstructed area are calculated. A border pixel with the highest priority is used as the center of a template block. A search for the best matched candidate template is performed in the reconstructed area. Distortion metrics between known pixels in the to-match template and corresponding pixels in candidate templates are calculated and compared. The candidate template with the smallest distortion metric value is chosen as the best match. Corresponding pixels of the best-matched candidate template in the searching area are used as predictors of the unknown pixels in the template centered at the pixel with the highest priority, and the predicted pixels are marked as known. The process is repeated until all pixels in the current block are marked as known.
