Image segmentation is very essential and critical to image processing and pattern
recognition. This survey provides a summary of color image segmentation techniques …

Vector directional filters (VDF) for multichannel image processing are introduced and
studied. These filters separate the processing of vector-valued signals into directional …

An approach to obtaining high-resolution image reconstruction from low-resolution, blurred,
and noisy multiple-input frames is presented. A recursive-least-squares approach with …

Up to now, most of the color edge detection methods are monochromatic-based techniques,
which produce, in general, better than when traditional gray-value techniques are applied. In …

A new color edge detector based on vector differences is proposed. The basic technique
gives as its output the maximum distance between the vectors within a mask. When applied …

The processing of color image data using directional information is studied. The class of
vector directional filters (VDF), which was introduced by the authors in a previous work, is …

Semantic edge detection (SED), which aims at jointly extracting edges as well as their
category information, has far-reaching applications in domains such as semantic …

In the hue saturation intensity (HSI) space, a hue difference taking into account the hue
relevance is defined. A hue gradient operator is build up with this hue difference. Two color …

Edge detection is widely used for image processing to improve the detection and
classification of objects, segmentation, and extraction of other features. Satellite images are …

This paper proposes a novel edge detection method for both gray level images and color
images. The 3× 3 mask in the image is considered and two pixel sets S0 and S1 in the mask …
