问题 I've been searching for resources for number recognition in images on the web. I found many links providing lots of resources on that topic. But unfortunately it's more confusing than helping, I don't know where to start. I've got an image with 5 numbers in it, non-disturbed (no captcha or something like this). The numbers are black on a white background, written in a standard font. My first step was to separate the numbers. The algorithm I currently use is quite simple, it just checks if a

问题 I would like to capture the number from this kind of picture. I tried multi-scale matching from the following link. http://www.pyimagesearch.com/2015/01/26/multi-scale-template-matching-using-python-opencv/ All I want to know is the red number. But the problem is, the red number is blurry for openCV recognize/match template. Would there be other possible way to detect this red number on the black background? 回答1: Classifying Digits You clarified in comments that you've already isolated the

Classifying Digits You clarified in comments that you've already isolated the number part of the image pre-detection, so I'll start under that assumption. Perhaps you can approximate the

The numbers are black on a white background, written in a standard font. My first step was to separate the numbers. The algorithm I currently use is quite simple, it just checks if a column is entirely white and thus a space. Then it trims each character, so that there is no white
