Abstract-The paper proposes a colorfulness enhancement of pict orial images using based on based image classifiey chroma histogram. This approa ch firstly estimates strength of colorfulness of images and their types. With su ch determined information, the algorithm automatically adjusts image colorfulnes s for a better natural image look. With the help of an additional detection of s kin colors and a pixel chroma adaptive local processing, the algorithm produces more natural image look. The algorithm performance had been tested with an image quality judgment experiment of 20 persons. The experimental result indicates a better image preference.
Key words-colorfulness enhancement; image classifica tion; chroma histogram
