The availability of a comprehensive face database is crucial to test the performance of these face(More)
The performance of content-based image retrieval using low-level visual content has largely been judged to be unsatisfactory. Perceived performance could probably be improved if retrieval were based on higher-level content.

For example, an artist might want to retrieve an image (for use in an advertising campaign) that evokes a particular " feeling " in the viewer.

Epidural spinal cord stimulation has been demonstrated to help the recovery of walking abilities of patients with incomplete spinal cord injury when combined with partial weight bearing therapy. However, no work has been done in studying the dynamics of these signals generated with and without stimulation. We show that the underlying dynamics of such(More)
