Real-Time Smile Detection OpenCV Python With Source Code
The Real-Time Smile Detection OpenCV Python was developed using Python OpenCV, In this article, we are going to build a smile detector using OpenCV which takes in live feed from webcam. The smile/happiness detector that we are going to implement would be a raw one, there exist many better ways to implement it.
A Smile Detection OpenCV Python face data is stored as tuples of coordinates. Here, x and y define the coordinate of the upper-left corner of the face frame, w and h define the width and height of the frame.
The cv2.rectangle function takes in the arguments frame, upper-left coordinates of the face, lower right coordinates, the RGB code for the rectangle (that would contain within it the detected face) and the thickness of the rectangle. The roi_gray defines the region of interest of the face and roi_color does the same for the original frame.
In this Real-Time Smile Detection OpenCV also includes a downloadable Project With Source Code for free, just find the downloadable source code below and click to start downloading.
