Vector quantization and progressive image transmission using Kohonen self-organizing feature map

Vector quantization is implemented using a modified Kohonen self-organizing feature map algorithm, called KVQ. To alleviate edge distortion a classification technique is applied to vector quantization. The classification technique is based on edge detection, since the human visual system is more sensitive to edges. A simple spatial domain progressive image transmission is presented, which uses separating mean KVQ. In simulation results, very good intermediate images were obtained at reasonable bit rates
