A jupyter notebook that implements the Hough transform from scratch, and allows exporting the Hough accumulator image.
For example, if we take the following input image:
We perform a gaussian blur and Canny edge detection to find the edges:
We run the Hough transform, and preview the accumulator:
We then threshold this and detect the peaks:
We can convert these points from rho/theta to cartesian line coordinates, and plot them on our input image:
You can run this up in a single command using my python-opencv-notebook docker image:
- Run docker image
docker run --interactive --tty --init --rm --name opencv-notebook --publish 8888:8888 --volume `pwd`/data:/app/data alexlouden/python-opencv-notebook- Open localhost:8888 URL output by the previous command
