Abstract :
Unsupervised artificial neural learning algorithms have clearly demonstrated their practical value for vector quantization of speech and stationary images. We examine competitive learning as an adaptive compression algorithm for highly repetitious video signals such as those found in animated cartoons. The characteristics of animated video are presented and their suitability for compression are examined. An artificial neural network system based on the soft competitive learning algorithm is presented for the adaptive compression of these video signals. Based on comparisons with existing compression techniques, this investigation indicates that a compression ratio of better than 100:1 is a reasonable expectation
