edge curve detection

基本解释

Firstly edge detection method for cross-sections is expatiated, and a B-spline active contour based on adaptive FEM is proposed to fit the digital contour curve.
首先对断层图像的边缘提取方法进行了论述，针对得到的截面轮廓数字曲线，提出了一种基于自适应B样条主动轮廓拟合方法。
This paper attempt to summarize corner detection method in gray-level image, binary image and curve of edge, also to compare with many property of corner detection algorithm.
对灰度图像、二值图像、边缘轮廓曲线的角点检测算法进行综述，分析了相关的算法，并对各种检测算法给出了评价。
