METHOD AND APPARATUS FOR CLASSIFYING IMAGE BASED ON THE IMAGE FEATURE

摘要

One device and a kind of method enter business graphic image and shooting image more accurately for image of the classifying input picture that is arranged so that may to classify. One color space conversion unit (105) converts one for each input picture and forms color space by brightness and saturation degree component. One Luminance Analysis unit (110) calculates a brightness frequency disribution of light component. One saturation analysis unit (120) calculates average staturation component. One image classification unit (130) compares an estimation function, and by its realization using the brightness frequency disribution of calculating and being averaged for saturation degree component, a threshold value is classified each input picture. One image classification unit (140) calculates a valuation functions, uses a brightness frequency disribution calculated and chromatic component averagely and the distribution of frequency.
