Edge Detection Examples

In following examples, we show that rolling guidance filter can be used to improve the edge detection results of classic Canny algorithm. By removing small structures from the image with our scale-aware filter, Canny algorithm performs better edge extraction and generates more reasonable results, less influenced by noise and small turbulence. For the Canny algorithm, the parameter is the default one in MATLAB.
