Abstract :
We present a new asymptotic quantization theory on a plane for a known smooth nonuniform data density. Based upon a two-stage model, we design a mapping for harmonic clusters. We discuss angular phase field, give a relative distortion mismatch for a case of asymptotic clusters and optimize over the cluster centers
