Abstract
A method for video coding includes determining whether any coding group of a transform block located within a second region has a non-zero coefficient. The transform block comprises a first region and the second region. Further, in accordance with a determination that no coding group of the transform block located within the second region has a non-zero coefficient, the method includes applying respective inverse transforms to transform coefficients of the transform block in horizontal and vertical directions.
