Edge lines are extracted automatically from image, by acquiring points of extremum of first directional derivative vertical with edge line with Fourier transform in frequency domain.

同时，参考一阶方向导数的数值来排除一些非边缘点（一阶方向导数的数值为常数者，零也为常数）。

Since the B-spline is a locally supported function, the smoothing formula can be strictly limited in a neighborhood of each point. The smoothing surface defined by the smoothing formula has the same convexity as that of the original image. Secondly, the edge points are detected by either computing the local extremum points of the directional derivative or computing zero-crossing of the second-order directional derivative of the smoothing surface. Finally, an example of an edge detector is given.

针对反卷积视觉模型的病态性，增加了适当的约束，给出了基于低松弛迭代格式的快速自适应滤波算法，对于一个N×N输入图象，由于变换核的局部支撑性质以及低松弛迭代格式的引入，使得快速自适应滤波算法的计算复杂度降为象素个数N〓的线性量阶N〓，就最小二乘算法的复杂性而言，优于不动点迭代算法的O以及基于FFT的预处理共轭梯度算法的O。

Wool flake appears to be male masturbation femaly at the beginning, phenanthrene elder sister feels cole dishful, according to do; Wool flake appears again 69 type oral sex, two people are explicit, according to do; Then wool flake appears again shade is handed in, two people are illuminated of course do; Wool flake appeared back door is handed in, phenanthrene elder sister looks the face is aglowly, act like a spoiled child twist Ni to say the family is afraid of painful, in sharp edge sharp edge request, temptation and stimulate reflect next reluctance did.

毛片一开始出现女的为男的手淫，菲姐觉得小菜一碟，照做；毛片又出现69式口交，两人都不含糊，照做；接着毛片又出现阴交，两人当然照做；毛片出现了后门交，菲姐看得脸通红，撒娇扭怩说人家怕痛，在锋锋请求、诱惑和激将下勉强照做了。

The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.

利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进：首先由累加阵列确定同心圆的圆心，然后由圆心到各个有效边缘点距离的均值求出半径，从而检测出同心圆的圆心与边缘。

ABSTRACT Edge configuration and edge conditions as the key elements of high confinement operation regime for H-mode have been investigated extensively since H-mode was first discovered on ASDEX divertor tokamak in 1982 with NBI heating.
