图像平滑与边缘检测的迭代算法

An Iteration Image Smoothing and Edge Detection Algorithm

图像平滑和边缘检测是图像处理、计算机视觉等领域研究的经典问题。区别以往对这两个问题独立求解的做法,文中作者将图像平滑与边缘检测问题结合起来综合考虑。首先,提出了基于全局边缘特征的边缘检测算法并对自适应平滑算法进行了改进。然后,利用迭代处理的思想对图像进行平滑和边缘检测,得到了迭代的平滑与边缘检测算法。实验表明,该算法可以有效地解决平滑过程中的细节保持和边缘检测时剔除伪边缘这两个难题。

Image smoothing and edge detection are classic problems in image processing field, instead of ignoring the relationship between the two problems and solving them independently, the author tries to use iteration method to solve this two problems by combining image smoothing with edge detection. Tests show that this method is available to keeping details when Smoothing and eliminating pseudo edges when in edge detection.
