OpenCV computer vision -- image threshold processing and adaptive threshold Otsu

Threshold processing refers to eliminating pixels in the image that are higher or lower than the threshold. Image threshold processing is mainly to set a threshold: greater than this number is given a value, less than a number is given another value, and the pixel value of the image is changed into the middle of two gray values to realize image ...
