Adaptation of Apple's Breakfast Finder app that recognizes handwritten digits during live capture.
Works best if the digit is on a rectangle such as a Post-It note. 50% of the time it works 100% of the time.
Recognizes rectangles through a VNDetectRectanglesRequest then feeds that to a VNCoreMLRequest using classifier trained on MNIST data by Apple.
Classification of the digit as well as confidence is shown on screen.
