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 (α(B, W), β(B, W)) indicating minimal variation of a discrete function P(x, y) inside a spatial aria of block B with weights W.
