  • Scan encoding of two dimensional pictorial entities
    Patent number: 4107648
    Abstract: A graphic arts image is partitioned into two-dimensional geometrically related pictorial entities known as "blobs" which are susceptible of identification by a number of parameters. An entire picture is scanned, a line at a time, and encoded with variable length Elias and Huffman codes, where the Huffman codes are in accordance with the relative frequencies of particular blob parameters of an ensemble of images, of which the images scanned are particular members thereof. The codes of each scanned line are generated, in real time, solely by comparisons with the immediately preceding scanned line.

  • Variable length codes for high quality image encoding
    Patent number: 4103287
    Abstract: A graphic arts image is partitioned into two-dimensional pictorial entities known as "blobs" which are susceptible of identification by a number of parameters. An entire picture is scanned and the relative frequencies of particular blob parameters are used to develop modified variable-length Elias-Huffman codes representative of the parameterized picture information in compacted form. Efficient storage, retrieval and transmission of large sets of high fidelity picture data are thereby facilitated.
