Paper Abstract

Pyramid codes such as 3-D subband coding, wavelet and fractile can be implemented with much simpler encoders and decoders than DCT-based compression systems. Since they do not use blocks, they do not suffer from blocking artifacts. They are particularly useful when the cost of the encoder is a concern, such as picture phone, teleconferencing, and camcorders. If used in production, post-production processing can be implemented without degradation. A programmable real-time encoder and decoder have been constructed for evaluating color 3-D subband coding algorithms. The results of tests with this hardware are presented for a wide range of compression ratios as well as the post-production processing of compressed video.
