Abstract

Enhancement of contrast in an image is a vital process of image processing, it increases the intensity of image pixels. By enhancing the contrast of an image, the quality of the image will be increased.The anticipatedtechniqueis the combination of non-subsampled contourlet transform and bilateral filter. The key contribution of this paper is the usage of a weighted mean separated sub-histogram equalization technique for increasing the contrast of medical ultrasound images. The performance of the proposed technique provides improved contrast enhancement features when related with the existing methods such as contourlet transform and Histogram Equalization in terms of structural similarity index matrix, PSNR and Absolute Mean Brightness Error.
Keywords:
    Bilateral filter weighted mean separated sub-histogram equalization non-subsampled contourlet transform ultrasound image
