Corel Image Features (layoutHistogram) 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 represent the color histogram layout of each one where HS color space is divided into 8 subspaces (8 colors : 4 ranges of H and 2 ranges of S). Moreover, each image is splitted into 4 sub-images (one horizontal split and one vertical split). The value in each dimension is the density of each color in the entire sub-image.

Note that this dataset has only data from 66616 images, due to the data related to 1424 images (ID: 62482-63905 ) were missing in the original source (UCI Repository).
