The problem of determining the location and orientation of straight lines in images is of great
importance in the fields of computer vision and image processing. Traditionally the Hough …

A generalized multidimensional Wiener filter for denoising is adapted to hyperspectral
images (HSIs). Commonly, multidimensional data filtering is based on data vectorization or …

We derive a stable technique, based upon matrix pencils, for the reconstruction of (or
approximation by) polygonal shapes from moments. We point out that this problem can be …

We establish a set of results showing that the vertices of any simply connected planar
polygonal region can be reconstructed from a finite number of its complex moments. These …

A generalized multidimensional Wiener filter for denoising is adapted to hyperspectral
images (HSIs). multidimensional wiener filtering (MWF) uses the signal subspace of each n …

Image superresolution refers to image processing algorithms which produce high quality,
high-resolution images from a set of low quality, low-resolution images. In many visual …

This paper describes a new framework, called repulsive attractive (RA) network for baseline
extraction on document images. The RA network is an energy minimizing dynamical system …

Based on wavelets, a theoretical method has been developed to process multi-gray level
documents. In this method, two-dimensional multiresolution analysis, a wavelet …

The recognition process of natural scenes is complicated at present, and images themselves
may be complex owing to the special features of natural scenes. In this study, we use the …
