img2ascii

My new project is an image to ascii converter. I have not read any howtos on it so I'm relying completely on myself and I might completely wrong with my basic approach. The idea is to apply an edge detection filter on the image. Then the image is divided into smaller patches and for each patch the  nearest neighbor out of a set of predefined ascii chars is selected. I don't know about the complexity of the project yet, but I hope my idea will work. As usual, any (working or not) results can be found on my github repository:
