WebChapter outline. Morphological operations can be used to refine or modify the shapes of objects in images. Many morphological operations can be applied to binary images to improve an image segmentation. Grayscale morphological operations can also be used as processing steps before binarization, or to help identify regional maxima and minima. WebJul 27, 2024 · Simple Thresholding is also known as Binary thresholding. This technique sets a threshold value and compares each pixel to that particular threshold value. If the pixel value is less than or equal to the assigned threshold, then the pixel value is set to zero or to the maximum value. Implementation of Simple Thresholding using OpenCV:
