摘要
拉普拉斯算子是经典的边界检测或增强的图像处理方法。对给出的模型图像求出拉普拉斯算子x/y/xy方向边界的输出图像,用算例分析了噪声对拉普拉斯算子输出图像的影响。对噪声图像经过高斯滤波后,再使用拉普拉斯算子得出较理想的边界增强图像。
Laplacian is a classic edge detection or image en- hancement processing method. Edge detection image is given from the model image by Laplacian with x/y/xy direction. The noise influence on the output image by Laplacian operator is analyzed with examples. The better edge enhanced image is gotten by using the Laplacian to Gaussian filtering noise image.
