Enhancement Technique of Image Contrast using New Histogram Transformation
This paper presents a preprocessing technique that can provide the improved quality of image robust to illumination changes. First, in order to enhance the image contrast, we proposed new adaptive histogram transformation combining histogram equalization and histogram specification. Here, by examining the characteristic of histogram distribution shape, we determine the appropriate target distri...
متن کاملA new approach to contrast enhancement in MAGICA gel dosimeter image with MRI technique
parameters that have to be measured in gel dosimetry. However, the resolution in gel is strongly dependant on gel composition. Selection of optimum method in dose response readout and proper values of parameters can result in noise reduction as well as improvement of contrast, and spatial resolution considerably. Materials and Methods: MAGICA polymer gel dosimeters were manufactured and irradia...
متن کاملDeveloping 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 کاملSatellite Image Enhancement using Curvelet Transform
Satellite Images are used in many fields of research and enhancement of these images is a very important process. Satellite image enhancement is done using various transform techniques, filters and interpolation methods. This paper discusses a method of satellite image enhancement using Curvelet transform and interpolation technique. The quality of the enhanced image is measured using parameter...
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 ...
