Let us understand how to find contours in an image using scikit-learn library − Example import numpy as np import matplotlib.pyplot as plt from skimage import measure x, y = np.ogrid[-6.7:np.pi:215j, -1.2:np.p

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 iso-valued 轮廓。 使用“marching squares” 方法计算特定级别值的输入二维数组的iso-valued 轮廓。数组值是线性插值的,以便为输出轮廓提供更好的精度。 参数: ...
Consider the following to be your original image: Assume that the following region in red is your region of interest (ROI), where you would like to find your contours: First, construct an image of black pixels of the same size.It MUST BE OF SAMEsize: ...
或者更好的是，由于我的输入都是一行，是否有一种方法可以防止findContours为单个垂直段找到多个等高线，这...

This can be done in multiple ways, such as having a count on the number of contours in an image and then using that to categorize the object shapes, for segmentation of images or cropping objects from the image that is being processed and many more such similar functions. ...
