Method and apparatus for compressing images containing optical symbols
 A method and apparatus for compressing documentary data, in which document data is first checked for the presence of decodable symbols such as bar code, Postnet code, or Maxicode (bullseye-type) code. If such symbols are detected, they are decoded, their boundaries defined, and identities recorded. Efficient compression is then performed on the decoded data, the symbol locations and the symbol identities, and higher fidelity compression techniques are performed on undecodable symbols such as signatures. Reconstruction of the image is performed by decompression of all data and superimposition of the decoded images over the undecodable images.
