Web8 de set. de 2014 · To perform thresholding we utilized the cv2.threshold function. OpenCV provides us with five basic thresholding methods, including: cv2.THRESH_BINARY , cv2.THRESH_BINARY_INV , cv2.THRESH_TRUNC , cv2.THRESH_TOZERO , cv2.THRESH_TOZERO_INV . OpenCV provides different types of thresholding which is given by the fourth parameter of the function. Basic thresholding as described above is done by using the type cv.THRESH_BINARY. All simple thresholding types are: cv.THRESH_BINARY cv.THRESH_BINARY_INV cv.THRESH_TRUNC cv.THRESH_TOZERO … Ver mais In the previous section, we used one global value as a threshold. But this might not be good in all cases, e.g. if an image has different lighting conditions in different areas. In that case, … Ver mais Here, the matter is straight-forward. For every pixel, the same threshold value is applied. If the pixel value is smaller than the threshold, it is set to 0, otherwise it is set to a maximum value. The function cv.threshold is used … Ver mais In global thresholding, we used an arbitrary chosen value as a threshold. In contrast, Otsu's method avoids having to choose a value and … Ver mais
