TEXTURE ENHANCEMENT METHOD AND APPARATUS REFLECTED HUMAN VISUAL CHARACTERISTIC ON SPATIAL FREQUENCY

摘要

A texture enhancement method and apparatus are disclosed for improving textures in which human visual characteristics are reflected in image data. The texture enhancement apparatus converts image data into an LMS cone signal, extracts a brightness signal from the changed LMS cone signal, converts the extracted brightness signal into a frequency domain, and applies a texture pattern to the converted frequency domain, thereby improving the texture. Generate data.
