Description: 数字图像的边缘检测
本科毕业设计（边缘检测是数字图像处理中的重要内容。本文首先对图像的边缘检测的各种算法和算子做了总结和分析。Canny最早提出了边缘检测的三条连续准则:最优检测结果、最优定位和低重复响应,并在这些准则的基础上得到了“最优线性滤波器”―高斯函数的一阶导数。经过十几年的发展,目前已经有了对这个准则的很多改进,本文也对这个方面的工作做了小结。Demigny在理论分析和实践的基础上给出了边缘检测的离散准则,并且证明在离散准则中Canny提出的第三个准则可以被阀值操作所取代。本文利用了数值方法求出了Demigny离散准则下阶梯形边缘检测的最优线性滤波器和对应着它的平滑算子。利用这个算子和Canny边缘检测方法得到了一个完整的边缘检测算法并用VC++实现了这种算法.从算法对大量图像边缘检测的结果来看,这种算法虽然简单但是效果很好,是边缘检测的一种很好的实用方法。-Edge detection is important in image procession. This paper made a summary and analysis of edge detecting algorithm and edge detector. Canny has proposed three continuous criteria to compare the performance of different filters: good detection, good localization and low-responses. Based on these criteria he got optimal filter for edge detection: derivative of Gaussian function. After more than ten years research, Canny’s theory has been ameliorated in many aspects, this paper also made a review of it. Based on the practice and theory. Demigny gave three discrete criteria for edge detection like Canny’s criteria and he has proofed that the third criterion can be replaced by an appropriate thresholding operation. This paper used numerical method to get the optimal filter and smooth operator under the Demigny’s criteria. Then I combine these filters and Canny’s edge detecting technique to get an integrated edge detecting algorithm. I have implemented the algorithm using VC++. From the res Platform: |

Description: Edge detection
We propose a edge detection framework that takes as its input a xation (a point
location) in the scene and outputs the region containing that xation. The xated
region is segmented in terms of the area enclosed by the \optimal" closed boundary
around the xation using the probabilistic boundary edge map of the scene (or image).
The probabilistic boundary edge map, which is generated by using all available visual
cues, contains the probability of an edge pixel being at an object (or depth) boundary Platform: |

unusually dense. Using methods from random matrix theory, we calculate the spectra of such networks in
the limit of large size, and hence demonstrate the presence of a phase transition in matrix methods for
community detection, such as the popular modularity maximization method. The transition separates a
regime in which such methods successfully detect the community structure from one in which the
structure is present but is not detected. By comparing these results with recent analyses of maximum-
likelihood methods, we are able to show that spectral modularity maximization is an optimal detection
method in the sense that no other method will succeed in the regime where the modularity method fails. Platform: |
