Abstract
An apparatus for video digital color pixel filtering and digital image processing that eliminates the need for Furrier Transforms, thus eliminating time-consuming multiplication and additions. It utilizes a new distributed computer architecture that operates in conjunction with First In First Out memories, utilizing simple software for each processor to minimize latency issues of real time interactive digital image processing. The distributed processing architecture is set up to operate in a manner similar to factory assembly lines, wherein FIFO's carry semi processed data from one processor to another. A unique memory based system is used to measure motion vectors including distances and rotational vectors, of moving objects moving in a six degree of freedom.
