Try both NxN, 2Nx2N and choose better one. */

Always use choose selected part mode. If NxN is chosen but cannot be applied (CB tree not at maximum depth), 2Nx2N is used instead. */

Base class for intra prediction-mode algorithms. Selects one of the 35 prediction modes. */

Algorithm that brute-forces through all intra prediction mode. */

Algorithm that makes a quick pre-selection of modes and then brute-forces through them. */

Algorithm that selects the intra prediction mode on minimum residual only. */

Utility class for intra prediction-mode algorithm that uses a subset of modes. */
