摘要
文章提出了一种基于粗糙集的图像边缘检测算法。首先 ,利用粗集理论将一幅图像划分为不同的子图 ,然后对子图分别去噪 ,再将两个去噪子图叠加得到最终去噪图像 ,最后 ,利用边缘条件属性对去噪图像做边缘检测。实验结果表明 ,该方法能满足对噪声图像进行边缘检测的要求。
In this paper,a noisy image edge detect method based on the rough sets theory is presented.Firstly,an image is segmented to different subimage by means of rough set theory.Then,subimages are denoised.Finally,the edge of denoising image is detected.The test result shows that the method can satisfy the request of the image edge detect.
