Snap N Paint

After a recent visit to see my niece and nephew I wanted to see if I could come up with an app that they might use. My idea was to create a paint by numbers style app but to source the picture to be coloured from an image.

The result is Snap N Paint, the picture is captured via the camera and processed using the OpenCV library sobel function, this provides an outline which can then be coloured in.

To make sure the correct colours are available in the palette, the original image is used. The user selects the area they would like to colour and the correct colour is set active.  

My current results are shown below (and my dodgy colouring skills), it is still a work in progress and I will probably never release it but it is quite fun if you have a stylus and a tablet.
