• Observation: blocks with strong contours and one dominant direction tend to be encoded with the same Intra directional mode in Texture and Depth
• Idea: when coding Depth, add the co-located Intra mode to the Most Probable Mode list when a dominant direction is detected
• Dominant direction is revealed by the presence of a single peak in the histogram of the gradient angle for the current block
• The Dominant angle revealed to be an effective feature for detecting blocks were inheritance givesimprovement. It is based on the detection
  of a single peak in the gradient angle histogram
• Inserting the inherited mode in the MPM list allows an average coding rate reduction of ≈1%,
