Ordering and formatting coded image data and reconstructing partial images from the data |
August 16, 1994 |
| Editing of information recovered from a relatively high speed communications medium such as a communications channel or magnetic tape often times allows only a portion of the information to be recovered. Storing information in complete segments from which portions of an image, called |

Method and apparatus for shuffling image data into statistically averaged data groups and for de |
April 5, 1994 |
| In a data compression process such as employed to compress video or other data, it is preferable not to compress the image data representative of the video image in a sequential format, or to take the data from the same area of the image. To equalize the information content of the data p |
