Full video: Writing in Air
Here in this program you can draw numbers in the air, and the trained neural network is used to identify what we drew.
The program was specifically configured to detect the tip of my blue pen.
Numbers can be configured using the "color_selector.py" file.
Each color lies in the specific HSV value range, hence taking advantage of this we can seperate any color from background.
Once the color is seperated, we can mark that point on the live video stream.
By pressing SPACEBAR we can start traking the points [ i.e. we can start drawing and it will stay ]
Once our drawing is completed [ drawing a number ], we can press Spacebar again to dave our drawing.
And then immediately the drawing is passed to our model to predict the number.
