Abstract :
A new localized approach to video teleconferencing is introduced using three-dimensional vector quantization (VQ). According to the proposed model, recent localized history of the sequences is used to encode present frames based on a hierarchical approach. The results indicate a high compression ratio of over 100:1 with a high quality of the perceived sequence
