WebWhat thresholding can do, at the most basic level, is convert everything to white or black, based on a threshold value. Let's say we want the threshold to be 125 (out of 255), then everything that was 125 and under would be converted to 0, or black, and everything above 125 would be converted to 255, or white. WebOpenCV is a cross-platform library using which we can develop real-time computer vision applications. It mainly focuses on image processing, video capture and analysis including features like face detection and object detection. In this tutorial, we explain how you can use OpenCV in your applications. Audience
