Abstract :
Storing full motion graphics animation or television images in a Personal Computer will generate huge amounts of data which will soon overwhelm even very large disc drives. Storing or retrieving images from a disc at 30 frames per second speed is not yet possible. The now common JPEG image compression standard can offer some relief at the price of generating more and more image distortions and visual artifacts with increased compression. A new “Lossless” image compression scheme, based on Autosophy networks, has been implemented and tested in an IBM PC (486). The algorithms operate by constructing pyramidal cascades of image fragments in a mathematical Omni Dimensional Hyperspace library which is stored in a disc file. Each image fragment of any size is stored only once to be reused and recycled in subsequent image storage. This will lead to saturation in the storage requirement in which the more images that have already been stored the less additional storage space is required to store additional images. The storage requirement for graphics images becomes totally independent of the image size, image resolution or the number of frames to be stored. Storage requirement only depends on the “Novelty” within the images or how similar the frames are to each other. Experimental data confirms the algorithms and suggests a highly superior method for storing images in PCs. But, real live animation or on-screen teleconferencing is only possible with specialized new graphics boards, which are slightly larger and slightly more expensive than conventional graphics boards
