Robust Kernel Regression for Restoration and Reconstruction of Images from Sparse Noisy Data
We introduce a class of robust non-parametric estimation methods which are ideally suited for the reconstruction of signals and images from noise-corrupted or sparsely collected s...

Direct image retrieval in JPEG and JPEG2000
Images are often compressed using JPEG or JPEG2000. Many retrieval systems operated in either uncompressed or compressed domains have been proposed. However, retrieving in multipl...

Synthesis and applications of lattice image operators based on fuzzy norms
In this paper we use concepts from the lattice-based theory of morphological operators and fuzzy sets to develop generalized lattice image operators that can be expressed as nonli...

Speckle Reduction on Ultrasound Image by Variational Methods and Adaptive Lagrangian Multipliers
Ultrasound images are corrupted by a multiplicative noise, the speckle, which makes high level analysis difficult. Within each resolution cell a number of elementary scatterers re...

Micro-CT System for Small Animal Imaging with Ultrafast Laser-Based X-Ray Source
A novel ultrafast-laser-based x-ray source is a promising candidate for replacement of a microfocal X-ray tube in a micro-CT system for small-animal imaging. We optimized conditio...
