1. A method of decoding Joint Video Experts Team (JVET) video, comprising:

  • defining a coding unit (CU) template within a decoded area of a video frame, said CU template being positioned above and/or to the left of a current decoding position for which data was intra predicted;

    defining a search window within said decoded area, said search window being adjacent to said CU template;

    generating a plurality of candidate prediction templates based on pixel values in said search window, each of said plurality of candidate prediction templates being generated using different intra prediction modes;

    calculating a matching cost between said CU template and each of the plurality of candidate prediction templates;

    selecting an intra prediction mode that generated the candidate prediction template that had the lowest matching cost relative to said CU template; and

    generating a prediction CU for said current decoding position based on said intra prediction mode.
