Quaternionic Analysis of Colour Images
The aim of this paper is to present the basics of a mathematical theory of a new Fourier transform of colour images from the point of view of Clifford analysis. Quaternionic-valued signals have long been used as a model for colour images and Fourier transforms for such signals have been studied in [3], [?], [6], [?], [7]. In this paper we use a version of the Fourier kernel markedly from those ...
متن کاملA Fast Algorithm for Exact Histogram Specification. Simple Extension to Colour Images
In [12] a variational method using C-smoothed l1-TV functionals was proposed to process digital (quantized) images so that the obtained minimizer is quite close to the input image but its pixels are all different from each other. These minimizers were shown to enable exact histogram specification outperforming the state-of-the-art methods [6], [19] in terms of faithful total strict ordering. Th...
متن کاملDensity-Based Histogram Partitioning and Local Equalization for Contrast Enhancement of Images
Histogram Equalization technique is one of the basic methods in image contrast enhancement. Using this method, in the case of images with uniform gray levels (with narrow histogram), causes loss of image detail and the natural look of the image. To overcome this problem and to have a better image contrast enhancement, a new two-step method was proposed. In the first step, the image histogram is...
متن کاملMelanoma Analysis using Dermoscopy Images
-Melanoma is the most dangerous type of skin cancer. Uncontrolled growth of cancer cells are mostly occurs in melanocytes. In spite of, to prevent its deadly consequences and for treatment to be efficient, to perform the early diagnostic of the melanoma efficient treatment is necessary. The diagnostic of melanoma, without any support is not possible, therefore dermoscopy was created. Dermoscopy...
متن کاملImage Retrieval System Based on Density Slicing of Colour Histogram of Images Subareas and Colour Pair Segmentation
Techniques to identify objects within an image and searching for similar objects in the database is not claiming a lot of progress, due to the limitations of the capabilities of the existing techniques and algorithms in image processing and computer vision to perform such task. In this paper, a new technique based on slicing the images to equally sub-areas, then applying the density slicing to ...
