SIVAL Image Repository

The SIVAL (Spatially Independent, Variable Area, and Lighting) benchmark SIVAL includes 25 different image categories with 60 images for each category. This benchmark emphasizes the task of Localized CBIR. The categories consist of images of single objects photographed against highly diverse backgrounds. The objects may occur anywhere spatially in the image and also may be photographed at a wide-angle or close up. We have created this benchmark since most of the Corel object images contain close-ups of an object that is centered in the image and typically occupies a majority of the image.

All pictures were taken with a Cannon s230 Digital Camera from a tripod at a resolution of 1024 by 768. For all pictures the flash was disaples, the JPEG setting was super-fine, the ISO speed was automatic and the white balance was on a manual setting.
