Image Quality Enhancement Using Pixel Wise Gamma Correction
This paper presents a new automatic image enhancement method by modifying the gamma value of its individual pixels. Most of existing gamma correction methods apply a uniform gamma value across the image. Considering the fact that gamma variation for a single image is actually nonlinear, the proposed method locally estimates the gamma values in an image using support vector machine. First, a dat...
متن کاملAn Enhancement of Images Using Recursive Adaptive Gamma Correction
The “Adaptive Approach for Historical or Degraded Document Binarization” is that in which Libraries and Museums obtain in large gathering of ancient historical documents printed or handwritten in native languages. Typically, only a small group of people are allowed access to such collection, as the preservation of the material is of great concern. In recent years, libraries have begun to digiti...
متن کاملAn Adaptive Image Enhancement Technique Preserving Brightness Level Using Gamma Correction
In this paper, we will discuss the development of the image enhancement techniques and their application in the field of image processing .The principle objective of image enhancement techniques is to process an input image so that the resultant image is more suitable than the original image for specific application. Traditional global histogram equalization usually causes excessive contrast en...
متن کاملA Comparative Study of Histogram Equalization Techniques and Adaptive Gamma Correction for Color Image Contrast Enhancement
The most noteworthy conclusion of image processing is a contrast enhancement. The most regular system for histogram equalization is utilized for retouching contrast within digital images. Histogram equalization is so advantageous and useful for image contrast enhancement method. Nonetheless, the traditional histogram equalization methods normally conclusion in surpassing complexity upgrades whi...
متن کاملMedical Image Contrast Enhancement Based on Gamma Correction
The luminance non-linearity introduced by many medical imaging devices often affects the performance of medical image processing techniques. Image enhancement plays an important pre-processing step in medical image processing methods. In this paper, we present a new automatic method for medical image contrast enhancement based on gamma correction. In this method, a global gamma value is calcula...
