Latest Patents

Sarwer holds a patent titled "Residual sign prediction of transform coefficients in video coding." This patent introduces a VVC-standard encoder and decoder that implement a residual sign prediction method. The method utilizes a sorting order of residual coefficients and an expanded region of a transform block (TB). By sorting transform coefficient signs based on corresponding QIdx values, the encoder and decoder achieve higher sign prediction accuracy, especially for larger transform coefficient levels. The prediction area is extended beyond the traditional upper-left 4×4 region, allowing for a maximum size of 32×32.
