Lossy Compression Technique Varies Data Quality in Response to Bandwidth or Time

Looking at ways to encode an image as a file, one byte in the file contributes information to one pixel (PPM files) or a small group of pixels (GIF, JPEG). In other image technologies such as wavelets, certain bytes contribute much more information than others. Lossy compression technique can vary data quality in response to bandwidth or time. Using this technology, data is encoded so that every byte in the file contributes a little information to all the pixels in the image. If a group of bytes is missing, an image can still be reconstructed from the remaining bytes.

The technology represents content as projections of highdimensional polygonal lines on smaller subspaces. The content can be reconstructed regardless of the order of the projections. Moreover, an approximation of the content can be reconstructed with a partial subset of projections.
