Patent number: 10171819Abstract: A method is provided for encoding a digital video with a video encoder that allows intra prediction of mode selection. The method includes dividing pixels from each intra prediction block into four groups based on phases of the pixels, progressively narrowing down a list of intra prediction modes over a series of stages based on a comparison of a cost value for each intra prediction mode at that stage against a threshold value, tentatively assigning the remaining intra prediction with the lowest cost value after the final stage to the block, calculating a heterogeneity index for each group of contiguous intra prediction blocks based on the tentative intra prediction mode selected for each block after the final stage, and finalizing the tentative intra prediction mode for each block if the group has a heterogeneity index above a predetermined threshold value.Type: GrantFiled: August 3, 2016Date of Patent: January 1, 2019Assignee: ARRIS Enterprises LLCInventors: Shailesh Ramamurthy, Anil Kumar Nellore, Padmassri Chandrashekar, Padmagowri Pichumani
