Summary

This chapter has shown several different types of image processing filters that can be used to generate various cartoon effects, from a plain sketch mode that looks like a pencil drawing, a paint mode that looks like a color painting, to a cartoon mode that overlays the Sketch mode on top of the paint mode to appear like a cartoon. It also shown that other fun effects can be obtained, such as the evil mode that greatly enhanced noisy edges, and the alien mode that changed the skin of a face to appear bright green.

There are many commercial smartphone apps that perform similar fun effects on the user's face, such as cartoon filters and skin color changers. There are also professional tools using similar concepts, such as skin-smoothing video post-processing tools that attempt to beautify women's faces by smoothing their skin while keeping the edges and non-skin regions sharp, in order to make their faces appear younger.

This chapter shows how to port the application from a desktop to an embedded system, by following the recommended guidelines of developing a working desktop version first, and then porting it to embedded, and creating a user interface that is suitable for the embedded application. The image processing code is shared between the two projects, so that the reader can modify the cartoon filters for the desktop application, and easily see those modifications in the embedded system as well.

Remember that this book includes an OpenCV installation script for Linux and full source code for all projects discussed.
