  An open hand shows a cat.

Inspiration

I've always been intimidated but interested by computer vision, so I tried my hand at it by following and modifying this tutorial by Up Degree.

What it does

This project detects the number of fingers raised on a hand and shows the corresponding image of a pet in response. A fist shows a dog. An open palm shows a cat. An OK sign shows a screaming cat.

How we built it

Using OpenCV, an image of the hand is captured. It is converted to grayscale before a Gaussian blur and thresholding is applied. Contours are drawn around the hand and the number of fingers is calculated using angles between fingertips.
