Abstract :
The performance of a shape adaptive activity controlled multistage gain shape vector quantiser for digital image compression is compared with that of more established full search multistage vector quantisation methods. The advantages of the former approach to the vector quantisation coding of images are clearly demonstrated via computer simulation of the respective coding algorithms.
