This article presents a new approach in image processing for detecting cracks in images of concrete structures. This method involves three steps: First; change the image to a gray and using edge of the image and
3.First theOtsu methodwas implemented to select a threshold in luminance field of the image automatically.首先使用最大类间方差法在舌图像的亮度范围内自动选取阈值,提取出较亮的舌体部分,然后再利用粗糙度信息进一步剔除非舌体部分,最后使用数学形态学的膨胀、腐蚀和开运算操作等方法进行后续处理,得到最终结果,成...

Otsu's Method Otsu's method In computer vision and image processing, Otsu's method is used to automatically perform histogram shape-based image thresholding,[1] or, the reduction of a graylevel image to a binary image. The algorithm assumes that the image to be thresholded contains two ...
