A human model using polynomial convolution surface is presented which is modeled by articulated skeletons convolved with some kernel function. The convolution surface and curve correspondence theorem under orthogonal projection is presented. The human contour is approximated with a convolution curve and 3D human pose can be estimated using a nonlinear optimization algorithm.

首先建立了一种新颖的多项式密度卷积曲面人体模型，该模型由连接体线骨架与某种卷积核卷积而成，整个曲面是一张连续曲面，调节多项式和半径参数可以让人体任意变形；给出了正交投影下卷积曲面和曲线对应的概念和相关定理，为二维的图像轮廓和三维人体模型之间建立对应关系；根据正交投影下卷积曲面与曲线对应定理，用卷积曲线去逼近人体的图像轮廓曲线，从而估计和恢复出三维人体运动姿态。

Then, to each point in this contour, the corresponding points in both original images are found.

通过求出轮廓内任意插值点与中心点的位置关系，分别找出其在2幅源图像上的对应点。

Methods 34 cases of secondary cavernous transformation of portal vein confirmed by clinical corroborative data were reviewed;plain scan and contrast-enhanced spiral CT were performed in all patients;10 of 34 cases'imaging data were postprocessed with multi-planarreconstruction,contour re-establishand maximum intensity projectionon blood vessel.

搜集34例经临床证实的继发性门静脉海绵样变性患者的MSCT资料，所有病例均行上腹部螺旋CT平扫及三期增强扫描。10例采用多平面重组、曲面重组、最大密度投影等后处理方法进行血管成像。

The problem of contour segment of 2-dimensional image could not be gotten very well with wavelet transform in image processing is analyzed in this paper.

首先分析了小波变换在进行图像处理时不能有效表示直线/曲线的奇异性问题，然后研究了能够很好表示二维或更高维奇异性的Contourlet变换的基本原理。

In this thesis, we apply Coulomb's law and propose an external force to overcome the problem of traditional ACM that can not capture the cavities of an object. Assume that each node of a snake has its own electric charge, and the object boundary has opposite electric charge. Then object boundary will attract the nodes of the snake. This helps the contour easily to move to the object boundary.

本论文中，我们运用库仑定律的观念，提出了一个运用局部引力作为外力的方法，用以克服传统主动性轮廓模型在凹面处收敛不佳的缺点；假设物件边界带电，而主动性轮廓模型的结点带与物件边界相异之电荷，则物件边界会吸引著主动性轮廓模型各结点，使得模型曲线更容易靠近物件边界。
