Distributed-Cannny-Edge-Detector

As per http://ieeexplore.ieee.org/document/6774938/
Download all files into same directory along with the test image, and run dist_canny() with full name of the image. For eg. dist_canny('lena.png')

1. The original image

2. A random block

3. After applying edge filters

4. After non-maximum suppression

5. After hysteresis tracking

6. Final result

Unfortunately, getting good results for an image requires manipulation of free parameters such as threshold for hysteresis tracking. I've used values recommended in the original paper.
