Let's make a real-time Facial Landmark Detection using OpenCV, Python, and Mediapipe API. It detects 468 facial landmarks in real time. Facial Landmark Detection is used for AR (Augmented Reality ...

Gradient calculation (Sobel Operators) - to detect edges; Gradient Magnitude Thresholding - to get rid of spurious response to edge detection; Double threshold - to determine potential edges; Edge ...
