Image Thresholding with OpenCV and Python

Oct. 24 2022 Yacine Rouizi
OpenCV Image Processing Computer Vision

Image thresholding is one of the most basic types of image segmentation. It consists of converting an image (a grayscale image) into a binary image (black and white image). In simple thresholding, we manually set a threshold value T and compare ...
