Find contours skimage
WebFeb 4, 2024 · Hey @steersteer it’s True that the result of the active contours is not what you would expect. I can try to see if changing the parameters improves the result. But just to be sure, is trab_1.tiff the real image on which you want to find the contour? Because on an image which is already binarized (or if not could be easily binarized using for example … Webfind_contours skimage.measure.find_contours(image, level=None, fully_connected='low', positive_orientation='low', *, mask=None) 在二维数组中查找给定级别值的等值线。 使用 "行进方阵 "方法来计算输入二维数组的等值线,以获得一个特定的水平值。
