High quality reproduction of color images

Abstract

In this thesis, we describe another adaptive color image quantization algorithm with spatial resolution fixed. The research is motivated by the desire to display high quality color images with small frame buffers. It is demonstrated that many color images which would normally require a frame buffer having 15 bits per pixel can be quantized to 8 bits per pixel which little subjective degradation. In most cases, the resulting images look significantly better than those made with other image enhancement techniques such as filtering, dithering, or uniform quantization and can be generated in shorter time compared with other adaptive color image quantization methods, with some improved appearance.
