OpenCV Python Hough Line Transform (Line Detection Algorithm Explained + Code)

In this video, I will go over hough line transform in OpenCv with Python using VS Code. Hough line transform is a method to find lines in an image by parameterizing a line in polar coordinates and bin counting those parameters to find the high occurrence.

how do we decide what should be the ideal number of lines like when you changed some threshold values and we could see the number of lines changing?

Thank you for sharing this,

Is there a solution to consolidate multiple closely parallel lines detected by my code into a single line?
