Web26 de abr. de 2024 · Color-spaces is a process to break a color image into different components of images. There are many color space in image processing like RGB, HSV, CMY, etc. We can do use color-spaces to break down the images and find the most suitable image component for the threshold. La*b* and HSV color space. WebIn OpenCV, cv2.adaptiveThreshold () is used for adaptive thresholding. The types of adaptive thresholding are: 1. cv2.ADAPTIVE_THRESH_MEAN_C: Where threshold value = (Mean of the neighboring values – constant. It is the mean of the block size of a pixel neighborhood subtracted by the constant value.
