Medical Image Contrast Enhancement Based on Gamma Correction

  title={Medical Image Contrast Enhancement Based on Gamma Correction},
  author={Karuppanagounder Somasundaram and P. Kalavathi},
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 calculated based on the image cumulative histogram without any knowledge of the imaging device. We evaluated… CONTINUE READING
