本文将偏微分方程(PDE)构造曲面技术应用于图形变形处理中。利用PDE方法构造的曲面光滑,可控性好的特点,在起、止画面之间构造PDE曲面,然后将其按某个参量不变剖分,从而获得中间逐层过渡面,完成二维图形变形。

A hierarchical non-linear method for image registration was presented, which integrates image segmentation and registration under a variational framework. An improved deformable model is used to simultaneously segment and register feature from multiple images. The objects in the image pair are segmented by evolving a single contour and meanwhile the parameters of affine registration transformation are found out. After that, a contour-constrained elastic registration is applied to register the images correctly. The experimental results indicate that the proposed approach is effective to segment and register medical images. 展开更多
