A system and method may compress a digital image. A storage unit may store a dictionary having a plurality of predetermined template patterns each identified by a code. A decomposition module may divide the image into a plurality of sub-regions. A compression module may select a template pattern from the dictionary that most closely matches an image features for each sub-region. The compression module may generate a compressed data set for the image in which each sub-region is represented by a code identifying the template pattern selected therefore. Once the data is compressed, a decompression unit may reconstruct the image. The decompression unit may use the code from the compressed data set to retrieve the template pattern from the dictionary for each sub-region and may reconstruct a full image by combining the template patterns for all of the sub-regions. An output device may display the reconstructed image. |
