基于MatLab不同平滑处理对边缘检测效果的影响

图像进行边缘检测前需要时图像进行预处理。常用的方法是均值滤波、中值滤波和高斯滤波．不同的图像预处理对边缘检测产生不同的影响．有些甚至影响到边缘的完整性和可靠性。利用MatLab进行仿真，对不同的预处理结果进行分析比较，得出不同的图像预处理对常见几种边缘检测的影响。

Sorting Algorithm without Changing the Data Position ＆ Dynamic Demonstration Based on MatLab

Image edge detection is required before the image preprocessing. The commonly used method is the mean filter, median filter and Gauss filter. Different image preprocessing have different effects on the edge detection, and some even affect the integrity and reliability of the edge. Uses MatLab simulation, analysis and comparison of different pretreatment results, works out the ef- fect of image preprocessing of several common edge detection.
