A matrix quantizer for image processing
K. S. Thyagarajan, H. Abut, H. Bheda · 2005
This paper discusses a matrix quantizer design algorithm for image encoding problems. The design algorithm is aimed at producing a codebook of matrices which are, at least, locally optimum with respect to a distortion measure. We have considered the squared error distortion measure in this work and generated codebooks based on a training sequence consisting of a number of pictures of different bit rates. The preliminary results show promise for further work in this direction.
