lab-canny-filter

Canny edge filter implementation. Extracts sharp edges from any input image.

Required environment

• Scilab
• SIVP Scilab toolbox

How to use

1. Open Scilab
2. Source the SIVP toolbox (from Scilab menu bar)
3. Source the canny_filter.sci file
4. Run the doCannyFilter() function in the prompt
5. Pick the image file to be filtered

Warning: do not pick a large image. This code being an experiment, it relies on the implementation of custom low-level mathematical operations, such as the convolution operation. To speed things up, you may use Scilab native conv2() function instead.
