1. A system, comprising: an image segmentation engine running on a host, which in operation, decomposes a compound image into one or more original image layers; a layer recomposition engine running on the host, which in operation, identifies “don't care” blocks in each of the one or more original image layers; recomposes the one or more original image layers into one or more corresponding new image layers having new dimensions by skipping the “don't care” blocks in the one or more original image layers, wherein no value is assigned to each of the skipped “don't care” blocks in the one or more original image layers; a layer compression engine running on the host, which in operation, processes and compresses each of the one or more new image layers, wherein each of the one or more new image layers has an associated compressor, the associated compressor being selected based on a content of the new image layer.
