本文从已知图像噪声统计的理论考虑出发，导出了一种选择边缘强度图阈值的广义技术。描述了一种利用一对图像估计图像噪声的均值和方差的技术。阈值选择技术可以应用于任何单一的数字边缘算子，并已扩展到边缘算子的组合使用。下面给出了使用这里开发的技术的两个阈值边缘映射示例。
This paper derives a generalised technique for selecting thresholds of edge strength maps from theoretical considerations of the known noise statistics of the image. A technique is described for estimating the mean and variance of the noise of an image using a pair of images. The threshold selection technique can be applied to any single digital edge operator and has been extended for use with combinations of edge operators. Two examples of thresholded edge maps using the techniques developed here are shown.
