Magnetic Resonance (MR) images often exhibit grayscale nonuniformities, caused by radio frequency (RF) coil design or acquisition sequences. Many algorithms to remove these nonuni...
Tracking multiple people in a dynamic environment is important in many applications. Recent research in this area has focused either on geometric analysis or appearance models. In...
We provide a new comparison between hexagonal and orthogonal lattices, based on approximation theory. For each of the lattices, we select the "natural" spline basis func...
A joint source channel coding scheme for error resilient image transmission is proposed. A practical image coder was introduced in [1] using modified Differential Pulse Coded Modu...

Sequential importance sampling (SIS), also known as particle filtering, has drawn increasing attention recently due to its superior performance in nonlinear and non-Gaussian dynam...

Multiple Description coding has been recently proposed for images and video transmission in packet erasure channels because of its good loss recovery capability. In this paper, we...
In this paper, we investigate the use of discriminant techniques in the elastic graph matching (EGM) algorithm. First we use discriminant analysis in the feature vectors of the no...

This paper describes the architecture of an 8x8 2-D DCT/IDCT processor with high throughput, reduced hardware, and a parallel-pipeline scheme. This architecture allows the process...
We consider the problem of automatically learning color enhancements from a small set of sample color pairs, and describing the enhancement by a three-dimensional look-uptable tha...
In this paper, we present a no-reference video quality metric that blindly estimates the quality of a video. The proposed approach makes use of a data hiding technique to embed a ...
