摘要
针对LOG算子的不足之处,提出了一种激光雷达图像的边缘检测改进LOG算子算法:用二维自适应Wiener滤波代替Gaussian滤波。仿真结果表明:对于含有高斯噪声和乘性噪声的激光雷达图像,该算法能够有效提高LOG算子的边缘检测能力。
Edge detection is an importance field in image process. After analyzing the theories of LOG operator, a modified algorithm is proposed in the paper. Using two-dimensional adaptive Wiener filtering instead of Gaussian filtering enhances LOG edge detection of Laser Radar imaging. The simulation results show that the method is effective in edge detection of laser radar image noised by Gassian noise and Speckle noise.
