说明：  Prostate cancer is one of the major causes of death among Human. The most effective method for early detection and screening of Prostate cancers is Ultrasound mammography. Ultrasound Mammography is commonly used in clinical practice for diagnostic and screening purposes. Reading mammography is a demanding job for radiologists, and cannot provide consistent results from time to time. Hence several computer-aided diagnosis (CAD) schemes have been developed to improve the detection of primary signatures of this disease. Digital images of mammography are displayed on a computer monitor and can be enhanced that is either lightened or darkened, before they are printed on film. Image processing techniques are widely used in several medical areas for image improvement in earlier detection and treatment stages, where the time factor is very important to discover the abnormality issues in target images, especially in various cancer tumors such as Prostate cancer, lung cancer, etc.
