Defining and laying out the view controllers

BeanCounter uses two view controllers. The first enables the user to capture and preview images of blobs. The second enables the user to review a blob's classification result and save and share the image of the blob. A segue enables the first view controller to instantiate the second and pass a blob and label to it. This is similar to how we divided the application logic in the project, ManyMasks, in Chapter 4, Detecting and Merging Faces of Mammals, so we are able to reuse some code.

Capturing and previewing blobs

Import copies of the VideoCamera.h and VideoCamera.m files that we created in Chapter 2, Capturing, Storing, and Sharing Photos. These files contain our VideoCamera class, which extends OpenCV's CvVideoCamera to fix bugs and add new functionality.

Also import copies of the CaptureViewController.h and CaptureViewController.m files that we created in Chapter 4, Detecting and Merging Faces of Mammals. These files contain our CaptureViewController...
