Abstract
A video encoding apparatus, a video decoding apparatus and method of encoding and decoding one or more images using various shapes of blocks. The video encoding apparatus is configured to determine a partition form, among candidate partition forms, for partitioning a current block into one or more partition blocks; generate one or more predicted blocks by performing a motion compensation with a scale factor applied to the one or more partition blocks; generate a residual block by subtracting the predicted blocks from the corresponding one or more partition blocks; generate at least one transform block by transforming the residual block; generate at least one quantized transform block by quantizing the at least one transform block; and encode the at least one quantized transform block, information on the determined partition form, and the scale factor into a bitstream.
