🤔Hough Transform and Line Detection with Python (detect lines on road) Explained

Taking a Udacity course on Self Driving Cars and came across the Hough Transform. This helps determine the most likely values to find a straight line. First we have to gray scale the image, then apply a Gaussian Blur, detect edges with the Canny Edge detection algorithm and finally detect straight lines.

Literally the best Hough transform video out there. Not long and over complicated but clear and straight to the point. Thanks heaps Mark!

Ur actually a god! Thx so much dude I really needed this video!

[datahacker]

Thanks man, the explanation is crystal clear

[prathamgandhi]

absolutely amazing video! Helped me so much with my project

[seba]

oh my god that is a fantastic explanation

[Nicolas-gjgf]

Very useful and understandable, thanks!

[nickolayliashuha]

well-explained, really a good one, if u have a course material misunderstanding. Keep going ;)

The reason Hough Transform is using polar coordinate is that of the vertical line

Great video! I got one question:
Can a sinusoidal function in hough space vote for more than 1 for the same box? Let me give an example:
Let's say we got three points in cartesian system and we have three different sinusoidal functions in Hough space corresponding to these points. Can a box in Hough space have more than three votes?
Thanks!

Can you take a video for the circle detection? Or generalized hough transform.

[nitish]

Slope of vertical axis in Cartesian coordinate system is always 90 degree or pi/2 rad. So still question remains same why do we need to do transaform?

working python code for line detection ?? anyone...please help...
