Developing a PC-based portal image contrast enhancement program
ABSTRACTBackground: Delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. The aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field. Methods: The software was written based on local enhancement of the pixel values in image ma...
متن کاملLow Light Image Enhancement via Sparse Representations
Enhancing the quality of low light images is a critical processing function both from an aesthetics and an information extraction point of view. This work proposes a novel approach for enhancing images captured under low illumination conditions based on the mathematical framework of Sparse Representations. In our model, we utilize the sparse representation of low light image patches in an appro...
متن کاملImage Contrast Enhancement
Purposes of Image Contrast Enhancement Enhancements are used to improve the appearance of an image and make it easier for visual interpretation, understanding, and analysis of imagery. There are a variety of point and local image enhancement operations. Point operations modify the DN of each pixel in an image independently, such as contrast stretching; Local operations modify the value of each ...
متن کاملA Fractional Differential Approach to Low Contrast Image Enhancement
In order to improve the image contrast, a 2-D isotropic fractional differential algorithm for contrast enhancement is constructed, and its structure and parameters on 8 directions are presented. This nonlinear filter algorithm is implemented on various low-contrast digital images and the contrast enhancement of image is controlled by fractional order. The capability of fractional differential m...
