Make a script where people upload a picture ( can be anything) and your Script must AUTOMATICALLY Convert it in a 3d drawing See this video: ( we need it 100% automatically! ) [login to view URL]
I have experience in Python language and used opencv before. I can use some shading or rearrange histogram values to make it appear like 3d but i don't think it will look like handdrawn 2d to 3d because artist makes each picture seperately with different coloring and stuff.
