In this paper, we propose an improved image fusion algorithm, which uses structural similarity to match the local energy of images. The local energy method can reflect the complemen-tarity between different types of images. But for grayscale images and infrared images which have very different intensity, the fusion between them can produce dark spots in the result. To avoid this, we introduce a structural...
Island detection is an essential protecting action in a distributed generating system. Island detecting is generally divided into two kinds, one is active island detecting, another is passive island detecting. The disturbance signal in active island detecting always causes pollution to power quality while the passive island detecting has long detecting time and large dead zone. All the existing detection...
How to build an accurate and reliable appearance model to improve the performance is a crucial problem in object tracking. Since the multi-view learning can lead to more accurate and robust representation of the object, in this paper, we propose a novel tracking method via multi-view learning framework by using multiple support vector machines (SVM). The multi-view SVMs tracking method is constructed...
Genetictic Algorithm (GA) is a widely-used high-efficiency random search and optimization method, which is geneticrated from evolution theory. This paper aims at overcoming the drawbacks of local convergence and not converging well to the globally-optimal solution, which usually exist in the course of solving optimization problems using Basic Genetic Algorithm(GA),and proposes a modified algorithm-...
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...
