Wavelet Denoising of Multicomponent Images, using a Noise-Free Image
In this paper, a Bayesian wavelet denoising procedure for multicomponent images is proposed. The procedure makes use of a noise-free single component image as prior information. T...

Blur Robust and Color Constant Image Description
An important class of color constant image descriptors is based on image derivatives. These derivative-based image descriptors have a major drawback: they are sensitive to changes...

Influence of the Presentation Time on Subjective Votings of Coded Still Images
The quality of coded images is often assessed by a subjective test. Usually the viewers get as much time as they need to find a stable result. In video sequences however, the view...

Gradient Adaptive Image Restoration and Enhancement
Various methods have been proposed for image enhancement and restoration. The main difficulty is how to enhance the structures uniformly while suppressing the noise without artifa...

Variational Local Structure Estimation for Image Super-Resolution
Super-resolution is an important but difficult problem in image/video processing. If a video sequence or some training set other than the given low-resolution image is available, ...

Direction-Adaptive Discrete Wavelet Transform via Directional Lifting and Bandeletization
We propose an adaptive lifted discrete wavelet transform to locally adapt the ltering direction to the geometric ow in the image. The proposed approach re nes previous directional...
