摘要
研究了干涉条纹边缘检测中的Sobel算子和Laplacian算子,针对二者使干涉条纹变粗和模糊的现象,提出了改进的Laplacian算子。该改进算子先对干涉条纹利用Gauss函数进行平滑,然后再作Laplacian变换。实验结果表明,改进的Laplacian算子克服经典算子的不足,获得清晰的条纹边缘,满足了干涉条纹后续处理要求。
In view of the disadvantages of being thickened and blurred interference fringe existed in the classical edge detection Sobel algorithm and the Laplacian algorithm,an improved edge detection algorithm is proposed.This new algorithm smoothes interference fringe by the Gauss function,then transforms interference fringe by the Laplacian algorithm.It has been proved that the new method is effective to solve the given problems.
