Abstract
A system and method for visual image compression and transmission offers significant bandwidth conservation while retaining high resolution imaging capability. Videograpic images are decomposed into detail levels, and images are delivered to a remote site display at a level of detail proportional to the perception level of a viewer. Images are transformed, quantized, coded and queued for transmission in accordance with their level of image detail. Image detail layers are transmitted as an inverse function of image displacement speed and as a direct function of image magnification. Images are constructed vertically with each additional queueing layer providing additional image detail. Higher priority layers are lossy encoded, while the lowest priority layers (highest detail levels) are losslessly encoded.
