WebHow Threshold Function Works in OpenCV? In order to create binary images, the images must be segmented. This segmentation is done by using OpenCV threshold. This thresholding is simple thresholding and adaptive thresholding. The pixel value which is used there has to be a corresponding threshold value which should be the same. WebJan 15, 2024 · To use OpenCV, simply import or include the required libraries and start making use of the myriad of available functions. Thresholding is a very popular segmentation technique, used for separating an object from its background.
