Visualize the Hough Transform process
Description
The Hough transform is a simple algorithm commonly used in computer vision to detect lines. This is an implementation in JS using the vector graphics library PaperJS.
Features
- Draw lines on the left and see the corresponding Hough space on the right
- Put your cursor in Hough space to see how it relates to what you've drawn (hover over the bright spots to see the lines detected)
Todo
- Ability to clear the canvas without refreshing the screen
- Fix screen resize to work in narrow windows
- Address performance issues when too many paths have been drawn
- Better colour scheme
- Ability to select the paths in Hough space and remove/highlight corresponding paths in the canvas
