In this paper, we propose a 3D template-based human action detection base on volume pattern matching. A volume pattern is obtained by detecting the principal plane from a space-time patch using the 3D moment-preserving technique. Instead of segmentation and detailed shape representation, the objective of this research is to develop and apply computer vision methods that explore the structure of a...
The relatively low quality of clinical untrasound images limits the success of early disease detection and diagnosis based on the images. Filtering speckle noise to enhance the quality of ultrasound images is thus very important to construct an automatic clinical diagnosis system. In this paper, we present an automatic liver cirrhosis diagnosis system using adaptive ultrasound image matching. Given...
In this paper, a new digital image stabilization involving multiple objects motion detection based on block-based Hough transform (HT) is presented. The line edges in a pair of edge blocks, where one is from current frame and the other is from previous frame are aligned to generate potential motion vectors to have votes on parameter voting matrix H using modified HT. The parameter voting matrix H...
