In computational anatomy, statistical shape model (SSM) is used for the quantitative evaluation of variations in the shapes of different organs. This paper focuses on the construction of a SSM of the liver and its application to computer-assisted diagnosis of cirrhosis. We prove the potential application of SSMs in the classification of normal and cirrhotic livers. In constructing a SSM of the liver,...
This paper has researched on the problem of centralized multi-sensor multi-target tracking against a background, which has a high demand of real-time and a relative demand of tracking precision, and analyzed the advantages and disadvantages of the existent classical algorithms theoretically in this environment. Based on the research and the analysis, general association algorithm has been extended...
In this paper, the method of GM (1, 1) modeling based on arccot(x) transformation is put forward. It is proved that the series after this transformation can not only needs the condition of modeling GM (1,1), but the smooth degree is much better than that by other transformations, so the method can widen the range of application of grey mode1. The practical application shows the effectiveness of the...
When the current block is at the edge of the objects, the prediction accuracy of H.264 intra-frame coding will be decreased. An enhanced intra prediction method is proposed in this paper based on the directional of intra prediction and correlation among adjacent pixels in the current block. The proposed algorithm use the pixels calculated already as the reference pixels to predict the rest pixels...
