Abstract
A method of encoding and decoding an image includes the following steps: subsampling the image to obtain a plural number of subsampled frames of spatially offset image-representative signals; transforming each of the subsampled frames to obtain a corresponding number of frames of transform coefficient-representative signals; forming vector-representative signals from corresponding coefficient-representative signals of the respective frames of coefficient-representative signals; transforming the vector-representative signals; quantizing the transformed vector-representative signals to obtain encoded signals; transmitting the encoded signals; receiving the transmitted encoded signals; and decoding the encoded signals to obtain a recovered version of the image.
