Canny edge detection - Python implementation

To execute the code, run the following command:

$ cd py-canny
$ python3 canny.py

The code will read all the images in pictures/origin/ folder, apply the Canny edge detection algorithm to them and save the results in pictures/result/ folder. In addition it shows the intermediate results of the algorithm, the final result and the execution time.

Execution time

The code has been tested on a computer with the following specifications:

  • Model: Asus ROG Zephyrus G14 GA401Q (2020)
  • OS: Ubuntu 20.04.2 LTS
  • CPU: AMD Ryzen 7 5800HS @ 3.20GHz
  • RAM: 16GB

The execution time of the code is shown in the following table:

Image Execution time (s)
1280x720 1.1
366x574 0.25
300x300 0.1
490x480 0.28
768x487 0.34
