Witryna8 sty 2013 · Simple Thresholding 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 to apply the thresholding. WitrynaStarting point for this is a binary image, e.g. made using thresholding. blobs = imread('../../data/blobs.tif') binary = threshold_otsu(blobs) imshow(binary) We can then split the touching object by only taking the binary image into account.
