Verfahren und Gerät zum Auswählen von Transformationskoeffizienten für ein Transformationskodierungssystem

摘要

A transform coefficient select method for a transform coding system of a still image and a motion image and an apparatus therefor 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, considering 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. <IMAGE>
