SOIL-47: Surrey Object Image Library
Why SOIL-47?It is often important to understand the behaviour of recognition methods when full projective or affine effects are present, in particular when only a single view is available to learn the appearance of a 3D object. With this objective in mind, a database of coloured household objects, many of the same shape, viewed over a significant portion of the viewing sphere was collected at the University of Surrey. The images show mainly multicoloured objects, many of which consisting of planar surfaces (boxes) and with generally complex colour structure. See an example of frontal views of all the objects. The database contains 24 objects with approximately planar surfaces and 22 complex scenes.

The DataThe grabbed images are in portable network graphics (PNG) format and their size is 576x720. Due to storage space limitations, a scaled version of the original images is available on-line with size 288x360. In addition, frontal views of the objects in the original size (576x720) were included in the on-line version of the database to allow testing of algorithms claiming scale invariance. No image processing was applied to the images. For the scaling the unix utility pnmscale was used.
The full-size image set can also be downloaded (~1.8 GByte).
