Summary

Second Sight now has some functionality that is more interesting than just reading and sharing camera data. Several filters can be selected and combined to give a stylized or vintage look to our photos. These filters are efficient enough to apply to live video too, so we use them in the preview mode as well as the saved photos.

Although photo filters are fun, they are only the most basic use of OpenCV. Before we can truly say we have made a computer vision application, we need to make the app respond differently depending on what it is seeing. This goal will be the focus of the next chapter.
