This application lets you draw simple math equations in the air and solves them . You can also use it to just draw something and save it.
The recogniton part is actually from another module Ive made before. PicCalc. https://github.com/SubhadityaMukherjee/Pic_Calc
Choose a color you will use to draw by running the command python range_det.py -f HSV -w
After that run python draw.py
