Method and system for video picture intra-prediction estimation

A system for video picture intra-prediction estimation, the system comprising:

• a memory device configured to store one or more video pictures;
• one or more processors coupled to the memory device and configured to:
• determine sets of M candidate prediction modes for ‘N×N’ pixel blocks included in a ‘2N×2N’ pixel block based on a predefined measure, each of the sets of M candidate prediction modes being determined for a respective one of the ‘N×N’ pixel blocks;
• determine whether any candidate prediction modes in the sets of M candidate prediction modes are common to all of the sets of M candidate prediction modes;
• and
• select one of a ‘2N×2N’ partitioning size and an ‘N×N’ partitioning size for the ‘2N×2N’ pixel block based on whether any candidate prediction modes in the sets of M candidate prediction modes are common to all of the sets of M candidate prediction modes.

A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to:

• determine sets of M candidate prediction modes for ‘N×N’ pixel blocks included in a ‘2N×2N’ pixel block based on a predefined measure, each of the sets of M candidate prediction modes being determined for a respective one of the ‘N×N’ pixel blocks;
• determine whether any candidate prediction modes in the sets of M candidate prediction modes are common to all of the sets of M candidate prediction modes;
• and
• select one of a ‘2N×2N’ partitioning size and an ‘N×N’ partitioning size for the ‘2N×2N’ pixel block based on whether any candidate prediction modes in the sets of M candidate prediction modes are common to all of the sets of M candidate prediction modes.
