Corel Image Features (colorTexture) dataset

1: Description.

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 (http://corel.digitalriver.com/). 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 extracted from a Corel image collection. The values represent the features of different textures measured in 4 directions of each image (horizontal, vertical, and two diagonal directions). These values are second Angular Moment, contrast, inverse difference moment, and entropy.

2: Type.			Unsupervised
3: Origin.			Real world
4: Instances.		68040
5: Features.		17
6: Missing values.	No
