-The paper is organized as following seven parts. Firstly, Section 1
gives an introduction of the background, significance and development of
the field of edge detection. And Section 2 introduces several classic edge
detectors and gives edge detection results of these methods and offers
some relative analysis and comparison. Then Section 3 offers specific
knowledge about the architecture and mathematical model of the BP
neural network. The specific algorithm and architecture of the proposed
new edge detector based on the statistical vector and the BP neural
network are introduced in Section 4. And an effective algorithm of edge
thinning which is helpful for accurate edge localization is offered in
Section 5. Experimental results and analysis of the performance of the
new edge detector are presented in Section 6. At last, the paper ends with
some further research plans mentioned in Section 7.

Description: 采用各向异性方法 填补一个缺损的轮廓，从而可以得到一个光滑完整的轮廓。- Completed contours correspond to ridges of an extension (ext) of the characteristic function of the uncompleted curve.
Anisotropic extension is performed on the characteristic function fbound of an image set given by
the binary map boundary to the whole image domain. Extension is initially driven by
\xi=(EigVect{1}, EigVect{2}) (which should match with the contour tangent direction)
computed as the direction of maximum coherence of the distance map to the contour to close.
It is updated every N iterations with DCV over the distance map to the ridges/thinning of the
evolved image.
Two different stop criteria are supported:
Number of Connected Components ( numcomp ). Contour Completion. Stop when the extended
contour (curve of level 1) has exactly Ncomp connected components.
Difference between two consecutive iterations ( tol )
Speed Stabilizes ( speed_stab ).
[extended]=ContourCompletion(BoundCond,f,DCVParam,StopParam,SaveParam)

Description: 快速并行算法是经典算法中比较好的一种细化算法,但其存在固有缺陷,可能产生信息丢失。为了克服这个缺点,提出了重合算法,最后为了减少计算时间和冗余信息,提出了基于模板保留的算法。-Fast parallel algorithm for the classical algorithm is a good thinning algorithm, but its inherent defects, the potential loss of information. In order to overcome this shortcoming, a coincidence algorithm, the final order to reduce the computing time and redundancy of information, the reservation-based algorithm for template.

Description: 建立一种可以区分输入图形的形态学算法，算法的输入是这三种图形的一种（这三个图形是对湖、湾、路段的图像细化后的结果），输出是对这三种图形的识别。假设这三种图形都是1个像素宽且完全连通的，然而它们出现的方向可以是任意的。-Can establish a distinction between the morphology of the importation of graphics algorithm input is a graph of these three (the three graphics on the Lake, Bay, after the section of the results of image thinning), the output is the three identification graphics. The assumption that these three are all graphics and a fully-connected pixels wide, but the direction they appear to be arbitrary.
