View-dependent precomputed light transport using nonlinear Gaussian function approximations
We propose a real-time method for rendering rigid objects with complex view-dependent effects under distant all-frequency lighting. Existing precomputed light transport approaches...

Visibility Sorting and Compositing Without Splitting for Image Layer Decompositions
We present an efficient algorithm for visibility sorting a set of moving geometric objects into a sequence of image layers which are composited to produce the final image. Inste...

TouchTone: Interactive Local Image Adjustment Using Point-and-Swipe
Recent proliferation of camera phones, photo sharing and social network services has significantly changed how we process our photos. Instead of going through the traditional dow...

Using Perceptual Texture Masking for Efficient Image Synthesis
Texture mapping has become indispensable in image synthesis as an inexpensive source of rich visual detail. Less obvious, but just as useful, is its ability to mask image errors d...

On the use of discrete Pascal transform in hiding data in images
The Discrete Pascal Transform (DPT) has been proved remarkably useful for edge detection, filter design, discrete-time signal interpolation and data hiding. In the present work a n...
