Fast TU size decision algorithm for HEVC encoders using Bayesian theorem detection

作者：

Highlights：

• We statically analyze the correlation between the variance of residual coefficients and the TU splitting mode.

• The correlation between variance of residual coefficients and transform size is exploited to reduce the number of candidate transform sizes for a given block.

• CU property and Bayesian theorem detection are utilized to reduce TU processing complexity.
