It can be anywhere from simple to hard depending on how varied your image set is and how robust you need it to be. For example are there pictures on the plate, etc.? Since you already have the binary image of the numbers and have labeled them you have already done the most difficult part, so in the simplest case you can probably just look at the area of the numbers - each number probably has a unique area. If two numbers have the same area, you might want to include the Euler number in your feature vector. Just keep adding measurements until you get a unique description (feature vector) of each number. |
