Stereo-Based Endoscopic Tracking of Cardiac Surface Deformation
We propose an image-based motion tracking algorithm that can be used with stereo endoscopic and microscope systems. The tracking problem is considered to be a time-varying optimiza...

Computation reduction in cascaded DCT-domain video downscaling transcoding
In this paper, we propose efficient techniques and architectures for realizing spatial-downscaling transcoders in the DCT domain. We also present methods for re-sampling motion ve...
