This study proposes a set of novel feature vectors for accurate differentiation of 3 typical types of liver space-occupying lesions in ultrasound images. Experiments were performed on 280 cases of liver images, including 112 cases of normal liver images, 90 cases of liver cancer images, 38 cases of liver hemangioma images and 40 cases of liver cyst images. First, we defined two types of region of...
Local histogram equalization (LHE) has been widely used in image enhancement. In medical ultrasound image the region of interest usually surrounds by large area of dark background, which contains little information but consume lots of computational resource. Direct application of LHE will not only be time-consuming but also affect the global visibility due to background distortion. Based on the characteristics...
