WebOct 29, 2024 · In general, there are several ways to obtain a binary image for boundary extraction. They include regular thresholding, Otsu's thresholding, Adaptive thresholding, and Canny edge detection. In this case, Otsu's is probably the best since there is background noise. First we convert the image to grayscale then perform Otsu's threshold … WebOct 1, 2014 · I'm trying to identify contours using a Canny filter in openCV and fill the contours, in order to create a mask.
