Abstract
Method and apparatus of image coding using block prediction (BP) allowing multiple block sizes are disclosed. According to one method, first distortion for the current block coded using BP with a first block size is derived using at least partial second distortion for the current block coded using BP with a first block size. According to another method, a flag indicating whether the BP using variable block sizes is enabled. According to yet another method, when a current block is coded using BP by partitioning the current block into multiple partitions, predictors for two partitions in different reconstructed pixel line groups are derived from different reconstructed pixel line groups. According to still yet another method, for coding image data in a non-444 color sampling format using BP, the predictors for chrominance pixels in the current block are derived from the predictors for the luminance pixels of the current block.
