Simple implementation of the Hough Transform algorithm that shows with very simple data how the algorithm works in detail, with focus on visualizing what happens. This project helped me a great deal in understanding more about the algorithm and improving also understanding the maths behind it.
Usage (needs Rust installed):
$ cd hough-transform-explained
$ cargo run
Compiling hough-transform-explained v0.1.0
Finished debug [unoptimized + debuginfo] target(s) in 1.39 secs
Running `target/debug/hough-transform-explained`
(rho) 127.2628 - round 127
(rho) 127.272415 - round 127
(rho) 129.64806 - round 130
Found line: 254/0 to 0/147 for rho = 127 and theta = 60
(clipped) from 154/58 to 0/147
After that you can open angle-visualization.png, houghspace.png and detected_lines.png in the current directory and inspect the output. The article for this code can be found at my website.
