Additional information

This dataset is a part of the Corel Image Features data set of the UCI Repository. It contains image features extracted from a Corel image collection ( The ID attribute is common in each of the 4 parts of the data set (colorHistogram, colorMoments, colorTexture and layoutHistogram).

In this part, the features represent the color histogram of each one where HSV color space is divided into 32 subspaces (32 colors : 8 ranges of H and 4 ranges of S). The value in each dimension is the density of each color in the entire image.
