초록
Recently, the Image compression methods in cooperation with Human Visual System characteristics are being investigated lively. In this study, we propose a new block coding method using i) non-linearity of HVS in the noticeable differences, ii) spatial easting effects, and iii) HVS sensitivity curve according to spatial frequencies. For vector quantization, the third scheme was dole effective than existing ones. We have applied this method on chest images and the results have shown better subjective qualities.
