Abstract
A method of compressing a current image of a sequence of images. The current image is transformed with a predetermined transform to provide a set of transform coefficients, which are divided into blocks. An encoding termination condition is determined for at least one block, and the block is encoded in a series of coding passes. In a current coding pass, a performance measure is predicted, and encoding is terminated if the performance measure satisfies the encoding termination condition. Different color components may be given different weightings.
