Early diagnosis of breast cancer helps to improve the successful treatment.Mammographic images are obtained from X-ray instrumentation. They are noisy and poor contrast due to ill performance of the hardware systems. Enhancement helps in improving the contrast of mammograms and reduces the false positive findings. Various enhancement techniques are(More)
-Coronary Artery Disease (CAD) is the disease commonly leads to Heart Attack. Heart Attacks are due to the formation of plaque along the inner wall of the coronary artery, which narrows the arteries and reduces the blood flow to the heart. In this paper the coronary artery is segmented using Graph cut algorithm, which includes vesselness measure, geodesic(More)
Modern multicore systems have a large number of components operating in different clock domains and communicating through asynchronous interfaces. These interfaces use synchronizer circuits, which guard against metastability failures but introduce latency in processing the asynchronous input. A speculative method helps to reduce synchronization latency by(More)
Contrast enhancement has an important role in image processing applications. Conventional contrast enhancement techniques often fail to produce satisfactory results for broad variety of low contrast images or cannot be automatically applied to different images, because their parameters must be specified manually to produce a satisfactory result for a given(More)
