Erosion and Dilation of images using OpenCV in python. Morphological operations are a set of operations that process images based on shapes. They apply a structuring element to an input image and generate an output image. Used to diminish the features of an image. http://opencv24-python-tutorials.readthedocs.io/en/latest/py_tutorials/py_imgproc/py_morphological_ops/py_morphological_ops.html

The function cv.threshold is used to apply the thresholding. The first argument is the source image, which should be a grayscale image. The second argument is the threshold value which is used to classify the pixel values. sushi vlijmen
