NEC Animal dataset consists of a sequence of about 5000 images from 60 toy animals taken at different poses. The pose changes continuously by putting each toy on a turntable. About 72 images are available per object. This dataset can be useful for performance evaluation of pose invariant object recognition or object categorization methods.

Thanks a lot Farid.
