摘要
通过Matlab对图像进行直方图分布,利用峰值找到图像阈值。对存在高斯白噪声的仿真图像进行去噪的效果分析,通过仿真的手法对其进行比较。最后通过Matlab的进行仿真,利用维纳滤波法、中值滤波法等有效手段,对图形图像进行处理分析,通过对比几组滤波方法发现维纳滤波法和中值滤波法都适合去除高斯白噪声。
The histogram distribution of the image is performed by Matlab, and the image threshold is found using the peak val-ue. The effect of denoising on the simulated image with white Gaussian noise （WGN） is analyzed and compared by simulation. Final-ly, through Matlab simulation and Wiener filtering method, median filtering method and other effective means, the graphics image isprocessed and analyzed. By comparing several sets of filtering methods, it is found that both Wiener filtering and median filtering aresuitable for removing white Gaussian noise.
