Blending of Contrast Enhancement Techniques for Chest X-Ray Pneumonia Images

Pneumonia, Lung cancer, Atelectasis are common lung diseases that cause notable deaths all over the world. These diseases can be treated well if identified through X-ray images of chest. The Chest X-rays images usually comprise of various discrete values of intensity and elevated contrast, and hence improper contrast and less brightness is observed. In this paper to confront the improper contrast of X-ray images, various contrast enhancement techniques are used such as DSIHE, BBHE, RMSHE along with PSO technique to enhance the X-ray images. Different parameters such as Entropy, PIQE, BRISQUE are used for objective computation results.
