Abstract

A digital video codec is presented, using a fast Gabor-like wavelet transform to produce a multiresolution data set. Three difFerent strategies are introduced to code different levels of the resolution in the pyramidal data, according to their visual importance. A hierarchical vector quantization is performed to exploit the inter/intra subbands correlations. A multiresolution block matching is proposed to generate the motion field in the scene. These motion vectors are then used to reduce the temporal redundancies. Simulations show good results in quality for medium bitrate transmission.
