Abstract
An image-feature extraction method is realized by identifying to which area in a color space with a plurality of areas previously segmented thereinto each pixel belongs based on a color of each pixel which forms a prepared image; and generating a color histogram of the image based on a number of pixels which belong to each of the areas. When the generated color histogram is extracted as feature parameters representing features of the image, a color space suited to human sensibility on color and also a color space segmented into areas each suited to human sensibility on color are used as a color space.
