我有一张图像，人眼清楚地包含几个(此处为 2 个)重叠的“花边”。 enter image description here

这源于一项相当冗长的实验图像分析。

红点是两个向量 px 和 py 中包含的所有点，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，一旦将数组作为 px 和 py 复制粘贴到编辑器中，这个 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])

本质上，这是两条线，每条线的宽度约为 6 像素。我想将它们分成不同的两行，这样从上到下的行就有 px_1,py_1，从左到右的行有 px_2,py_2。

到目前为止，我未能找到合适的关键字来找到此类算法。我想到的是一个 for 循环，它从一个末端开始，以这样一种方式完成具有像素位置的列表，即循环前进的方向永远不会超过相对于前面几个步骤的特定角度。这样，该算法将始终采用平滑穿过交叉点的像素集。然后只需从数据中删除新找到的行并重新开始即可。

你有什么更好的意见吗？

感谢任何反馈

最佳答案

Skeletonize图片。
按交叉点拆分(它有超过 2 个邻居)- 给你 4 个部分。
将方向相似的对连接在一起 - 你会得到 2 条骨架线。
通过接近度阈值将原始像素分配给每条线。
