| Abstract(in English) | When we see a binary black and white image, it appears, to our visual sense, to become clearer because of a pseudo halftone. We have investigated and presented a visual model for human visual information processing, which is executed through external world, retina and finally brain. We proposed an objective evaluation method of various modulation images using the above visual model. The Purpose of this paper is to compare PSNR, WSNR, average filter and measure of approximation using the visual model. We made extensive experiments for five kinds of modulation method- ordered dither method, least mean error, pulse density four division, simple two value, random dither- in which each of the images we evaluated both subjectivity and objectivity. The results of a series of experiments show that ranking by subjective evaluation dose not coincide with PSNR, WSNR, and average filter, but coincides with a measure of approximation using the visual model. |
