Interface Detection in Diffusion Tensor MRI
We present a new method for detecting the interface, or edge, structure present in diffusion MRI. Interface detection is an important first step for applications including segmenta...

Hiding correlation-based watermark templates using secret modulation
A possible solution to the difficult problem of geometrical distortion of watermarked images in a blind watermarking scenario is to use a template grid in the autocorrelation func...

Imperfect shadow maps for efficient computation of indirect illumination
We present a method for interactive computation of indirect illumination in large and fully dynamic scenes based on approximate visibility queries. While the high-frequency nature...
