  • Optimal intra prediction in block-based video coding to calculate minimal activity direction based on texture gradient distribution
    Patent number: 9451266
    Abstract: Simplified selection of optimal intra prediction in block-based video coding based on texture gradient distribution and minimal activity direction. The minimal activity direction is defined by a vector (?(B, W), ?(B, W)) indicating minimal variation of a discrete function P(x, y) inside a spatial aria of block B with weights W.
