I want to recognize numbers using gestures through coding. I've recognized using gesture library. Is there any possibility to recognize numbers perfectly?
Please suggest any sample code.

To detect the hand movements, several sensors exist, such as camera, depth- camera, and radio sensors. The signal at the output of these sensors is analyzed using suitable algorithmic techniques to detect a predefined hand gesture.
In this study, we propose the gesture recognition algorithm using support vector machines (SVM) and histogram of oriented gradient (HOG). Besides, we also use the CNN model to classify gestures. We approach and select techniques of applying problem controlling for the robotic system.
Recognition of Hand Gestures. When the fingers are detected and recognized, the hand gesture can be recognized using a simple rule classifier. In the rule classifier, the hand gesture is predicted according to the number and content of fingers detected. The content of the fingers means what fingers are detected.
A gesture is a movement of the hand, arms, or other body part that is intended to indicate or emphasize something, often when speaking. In other words, gestures are body movements that express something. For example, a wave of the hand is a common gesture used to say hello to someone.
What do you mean by perfectly? As in successfully detect the number the user intended to gesture 100% of the time? As long as your users are human, this isn't possible. 4 can look like 9, 1 can look like 7, and depending on how quickly they swipe, what started out as a 0 can end up looking like a 6 (or vice versa). Every individual gestures differently than everyone else, and every time you gesture a 4, it's going to look just a little more or less different from your 9, as well as all your other 4's.
One possible solution is to have your app contain a "learning mode" which asks the user to gesture out a specific digits several times, so that you can pick up on patterns (where they start, where they stop, how many swipes are included, how big it is), and use those to narrow things down when the app is actually used. Sort of like a good spam filter- It won't get you 100% detection rate, but it'll definitely get you a lot closer than not having a data set to work off of.
