Contrast and Brightness Enhancement for Low Medical X-Ray Images
Faisel G. Mohammed, Huda M. Rada, Sega G. Mohammed · 2013
Image enhancement techniques have been widely used in many fields, especially in medical scope, where the subjective quality of images is important for human interpretation (diagnosis). Denoising and contrast enhancement are important factors in any subjective evaluation of image quality. In the recent research work some techniques have been used to enhance medical images in the spatial domain using spatial filter (like, Sobel, Laplacian, and Smoothing). In additional, some logical and arithmetic operators have been used (like, AND, sum, subtract).A Hybrid strategy for image enhancement by combining spatial enhancement with power-law transforms function has been implemented. The effectiveness of this technique was evaluated using tested low medical x-ray images. The assistance criteria such as MAE (mean absolute error), and human visual was tested. The final results show that the suggested method is over tested images.
