How do you find the contours in OpenCV Python?

OpenCV has findContour() function that helps in extracting the contours from the image. It works best on binary images, so we should first apply thresholding techniques, Sobel edges, etc.

How do you count the number of objects in an image in Python?

To count the number of objects we will count the number of labels generated by simply using the len function on the labels list created and print the number of objects found in the picture.
