TL;DR
A recent project showcased on Maker Monday involves using a Raspberry Pi 3 Model B+ and a Raspberry Pi Camera Module 3 to detect iris color. The system utilizes OpenCV, a computer vision library, to process images and identify the color of a person's iris as they look into the camera. This project was developed by Srikrishna Karthick, a student working with the Indian Space Research Organisation (ISRO), who aimed to create a more engaging demonstration for a National Science Day event.
