 1 | # Hand-Timer-CoreML-Custom-Vision-ML-Model-iOS-Xcode
 2 | 
 3 | * Using Microsoft's Custom Vision "https://www.customvision.ai" I build a Core ML Model using hand images dataset of my own and created a model that can classify different hand gestures(static). It will get the image (input) from the custom camera feed in the iOS Application that i build and gives the output as the tag that was assigned to it while training. The hand can be Open Fist, Close Fist or there wont be a hand at all. It will classify between these 3 states.
 4 | * The application is a timer that has start stop reset functionality feature that will be controlled by your hand.
 5 | 
 6 | ### How it works
 7 | - Give access to the Camera
 8 | - Place your hand in front of the back camera, you can see your hand with a little transparency in the background of the app.
 9 | - If you put your open fist in front of the camera, the timer will start or resume if you paused(next point) in middle.
10 | - If you place closed fist in front of the camera, then the timer will be stopped or paused.
11 | - If you take away your hand then the timer will be reset to 00:00.00
12 | 
13 | ## Note
14 | * Xcode 9 and Swift 4 was used for this project.
15 | * The CoreML model for the hand detection is included in the project repository.
16 | 
17 | ## How it looks like

21 | 
22 | Try it out. Download the project and run it on your iDevice, it works like a charm.
