Let's say I have a small bitmap that contains a single digit (0..9) in handwriting.
Is it possible to detect the digit using a (two-layered) perceptron?
Are there other possibilities to detect single digits from bitmaps besides using neural nets?
Yes, you can use perceptron to detect hand-written digits as the Neural Network approach the problem in a different manner. The main idea is to take a large number of handwritten digits, known as training examples. You can see the training examples below:
