Summary
The Second Sight app can see now! At least, it can recognize any image from a predefined set and can draw a quadrilateral around that image. To a certain extent, this feature is robust with respect to scale, rotation, and skew. For example, the image can be tracked from various distances and angles of view.
Although we only added a single class in this chapter, we covered a lot of OpenCV functionality. Next, we will step back and consider how to integrate this OpenCV functionality with other types of interactive graphics. We will build a small game atop image recognition filters of Second Sight.
