Rate control for JVT video coding scheme with HRD considerations
The recent JVT video coding scheme (MPEG-4 AVC/H.264) is a promising technique due to its high coding efficiency. Hypothetical Reference Decoder (HRD) is a very important part in ...

Real-Time, Accurate Depth of Field using Anisotropic Diffusion and Programmable Graphics Cards
Computer graphics cameras lack the finite Depth of Field (DOF) present in real world ones. This results in all objects being rendered sharp regardless of their depth, reducing the...

Robust Facial Feature Extraction Using Embedded Hidden Markov Model for Face Recognition under Large Pose Variation
We propose an algorithm for extracting facial features robustly from images for face recognition under large pose variation. Rectangular facial features are retrieved via the by-p...
