In the third part of this series, we will be learning about analyzing contours. This is really important because by doing contour analysis you can actually recognize the object being detected and differentiate one contour from another. We will also explore how you can identify different properties of contours to retrieve useful information. Once you start analyzing the contours, you can do all sorts of cool things with them. The application below that I made, uses contour analysis to detect the shapes being drawn!
