Webb16 juli 2024 · In global thresholding, each pixel value in the image is compared with a single (global) threshold value. Below is the code for this. Here, we assign a value of “ val_high ” to all the pixels greater than the threshold otherwise “ val_low “. OpenCV also provides a builtin function for thresholding the image. WebbHow 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 …
