我有一个人眼清晰地包含几个（2个）重叠'鞋带'的图像。 enter image description here

这源于对实验的相当长的图像分析。

红点是两个矢量中包含的所有点，px和py，一个是红色像素的x_position，另一个是y位置。

  px= array([  0,   0,   0,   0,   0,   0,   1,   1,   1,   1,   1,   1,   1,

要重现图像，只要将数组作为px和py复制粘贴到编辑器中，此MWE就足够了

import numpy as np
plot_mtx = np.zeros( (5120,5120) )
px=...
py=...
window_size = max(px[-1]-px[0],[py[-1]-py[0]])
imshow(plot_mtx[min(px):min(px)+window_size,min(py):min(py)+window_size])

基本上，这些是两条线，每条线的宽度约为6像素。我想将它们分成两个不同的行，这样我就可以有px_1，py_1用于从上到下运行的那个，而px_2，py_2用于从左到右运行的那个。

到目前为止，我找不到合适的关键字来找到这样的算法。我要记住的是一个for循环，它从一个末端开始，以这样的方式完成一个像素位置的列表，循环进行的方向相对于前几个步骤永远不会超过某个角度。这样，算法将始终采用通过交叉点平滑交叉的像素集。然后，只需从数据中删除新找到的行并重新开始。

你会有更好的投入吗？

Answer 1

Skeletonize图片。
按交叉点分割（它有两个以上的邻居） - 这样可以得到4个分段。
将类似的指导对加入 - 你得到2条骨架线。
按照接近阈值将原始像素分配给每条线。
