Simple Hand Gesture Recognition Code - Hand tracking - Mediapipe

Goal of this gist is to recognize ONE, TWO, TREE, FOUR, FIVE, SIX, YEAH, ROCK, SPIDERMAN and OK. We use the LANDMARKS output of the LandmarkLetterboxRemovalCalculator. This output is a landmark list that contains 21 landmark. In the 02-landmarks.jpg picture below you can see the index of each landmark. Each landmark have x, y and z values. But only x, y values are sufficient for our Goal. If you dont want to copy/paste each the code on this gist, you can clone my forked version of mediapipe here: https://github.com/TheJLifeX/mediapipe. I have already commited all code in that repository.

We have five finger states.

//C++ copy files
#include <fstream>
std::ifstream  src("from.ogv", std::ios::binary);
std::ofstream  dst("to.ogv",   std::ios::binary | std::ios::trunc);
dst << src.rdbuf();

/* 
	the one-liner:
	std::ofstream(dest) << std::ifstream(src).rdbuf();
