In this section, we are going to describe how to process the received image in order to draw an image file on top of it. Now, a cascade classifier is run just as in the previous chapter. It is important to pay attention to the XML cascade file location. Throughout the code, we have used a helper function called getResourcePath, and we have used the convention of storing all the resources in the src/main/resources/ folder.
