【摘要】 简要介绍了几种经典的边缘检测技术,并在MATALB中利用这些算子对约束收缩引起的混凝土裂缝进行裂缝图像的边缘检测,通过对比几种算子的分析结果,总结出相对有效的裂缝图像边缘检测算子,为进一步施行裂缝表征参数的提取提供依据。更多还原

【Abstract】 Several kinds of classical flame image edge detection operators have been introduced.Then they were applied in edge detection of concrete cracking due to restrained shrinkage through MATLAB.The effective image edge detection operator was concluded by comparation.And that will afford gist for characteristic parameters for cracking.更多还原
