British Aerospace provided a database (which is part of the Sowerby Image Database) consisting of 119 coloured images of outdoor scenes.
The RGB image is a 24-bit colour digitised picture that has been calibrated to eliminate various undesirable effects in the image acquisition stages such as the systematic error in the colour levels introduced during the digitisation phase.
The images have been ideally segmented. This process consists in the splitting of the image in several regions which roughly correspond to the objects (or parts of an object) contained in the scene. Then the over-segmented regions corresponding to one object have been merged, whereas under-segmented regions have been further split.
The regions have been hand labelled and classified in one of 11 categories.
