WebMar 26, 2024 · Thresholding Thresholding transforms images into binary images. We need to set the threshold value and max values and then we convert the pixel values accordingly. There are five different types of thresholding: Binary, the inverse of Binary, Threshold to zero, the inverse of Threshold to Zero, and Threshold truncation. WebSimple Thresholding in OpenCV Simple thresholding is often referred to as global threshold as the thresholding function is applied equally to every pixel of the image, and the threshold value is fixed. The same threshold value is used for each pixel value.
