Ransak algorithm to find line parameters of an image and draw the line

Question

i have these two images :

and i should use ransak algorithm to find line parameters of them and draw the best line on them.

here is an implementation of ransak algorithm:

the algorithm's first step is to select random data from original data, how can i use image as input?

Answer 1

仅需查找图像中所有非零的点即可。使用numpy.where查找所有非零的坐标。

(y, x) = np.where(img)

img是图像，假设它是灰度的。 y是行位置，x是列位置。您将使用它们来输入帖子中看到的代码。
