A Hierarchical Parallel Processing System for the Multipass-Rendering Method
The multipass-rendering method integrating radiosity with ray-tracing gives one of the best solutions for synthesizing photo-realistic images. However, the method is also computat...

Non-Rigid Object Alignment with a Mismatch Template Based on Exhaustive Local Search
Non-rigid object alignment is especially challenging when only a single appearance template is available and target and template images fail to match. Two sources of discrepancy b...

Discriminative Descriptor-Based Observation Model for Visual Tracking
Varying illumination and partial occlusion are two main difficulties in visual tracking. Existing methods based on appearance information cannot solve these problems effectively s...
