Robust perceptual image hashing using feature points
Perceptual image hashing maps an image to a fixed length binary string based on the image's appearance to the human eye, and has applications in image indexing, authenticatio...

Non-robustness of statistics-based beamformer design in correlated MIMO channels
Recent attention on correlated multi-input multi-output systems has centered around the case of imperfect channel or statistical information at the transmitter. The focus of this ...

Fast Sampling of Implicit Surfaces by Particle Systems
Particle systems, as originally proposed by Witkin and Heckbert [17], are a powerful way to sample implicit surfaces since they generate almost evenly distributed samples over the...

Spatio-Temporal Fusion of Multiple View Video Rate 3D Surfaces
We consider the problem of geometric integration and representation of multiple views of non-rigidly deforming 3D surface geometry captured at video rate. Instead of treating each...

Assembly synthesis with subassembly partitioning for optimal in-process dimensional adjustability
Achieving the dimensional integrity for a complex structural assembly is a demanding task due to the manufacturing variations of parts and the tolerance relationship between them....
