Method and apparatus of context modeling for syntax elements in image and video coding

摘要

A method and apparatus for video and image coding using context modeling for video and images is disclosed. The selected context is determined from the set of contexts for the first syntax element at the first location based on statistics of the one or more second syntax elements at one or more second locations in the predefined area. The first syntax element is different from the second syntax element. The first syntax element is then encoded or decoded according to the selected context. In one embodiment, context modeling is applied to transform the coefficients. The first syntax element corresponds to coeff_abs_level_grater1_flag, and the second syntax element corresponds to significant_coeff_flag.
