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

摘要

A method and apparatus of video and image coding using context modeling for video and image are disclosed. A selected context is determined from a context set for a first syntax element at a first location based on statistics of one or more second syntax elements at one or more second locations within a predefined region. 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, the context modelling is applied to transform coefficients. The first syntax element corresponds to coeff_abs_level_greater1_flag and the second syntax element corresponds to significant_coeff_flag.
