Fast contrast enhancement by adaptive pixel value stretching

Enhancement of CT Images by Modified Object Based Contrast Stretching

The characteristic information of an organ lies in the texture of the image obtained by computed tomography imaging procedure. Therefore, enhancement of CT image aids a radiologist to better diagnose a disease which is a result of the enhanced/improved perceptibility and interpretability of the information present in the texture of the image. The present work proposes a method for texture enhan...

Evolutionary Contrast Stretching and Detail Enhancement of Satellite Images

In this paper we present a method of evolving the contrast characteristics of a satellite image by employing a real-coded genetic algorithm with subjective fitness. The contrast properties of an image are given by its contrast-stretching curve, and the task of the Genetic Algorithm is to evolve this curve in order to find the best shape according to some subjective fitness. The subjective fitne...

Fuzzy Based Contrast Stretching for Medical Image Enhancement

Contrast Stretching is an important part in medical image processing applications. Contrast is the difference between two adjacent pixels. Fuzzy statistical values are analyzed and better results are produced in the spatial domain of the input image. The histogram mapping produces the resultant image with less impulsive noise and smooth nature. The probabilities of gray values are generated and...

Performance Analysis of Contrast Stretching Enhancement Techniques for Medical Images

Leukemia is a malignant disease (cancer) that affects people in any age either they are children or adults over 50 years old. Nowadays, there are screening system guidelines for leukemia patients. The screening result from looking at a sample of patient blood, can determine the abnormal levels of white blood cells, which may suggest leukemia for further diagnostic stage. Therefore, medical prof...
