ABSTRACT:
A transform coefficient selection method and apparatus for coding a still image and a motion image in a transform coding system are provided, which can receive an input block and far better enhance a quality of picture of a restored image by selecting a predetermined number of transform coefficients taking into account an amount of variation of blocks due to an error between a block restored by a local decoder for each transform coefficient and the input block and an amount of variation of bits generated by selecting each transform coefficient.
