WebThis is not the right way to threshold: otsu_img [otsu_img > keys ['pixel']]=1 and otsu_img [otsu_img < keys ['pixel']]=0. What you're doing here is setting all pixels above your threshold (let's say 130) to 1. Next you're finding all pixels below 130, including those you just set to 1, and setting them to 0. WebDec 8, 2024 · In order to do this we will use mahotas.thresholding.bernsen method Syntax : mahotas.thresholding.bernsen (image, contrast_threshold, global_threshold) Argument : It takes image object and two integer as argument Return : It returns image object Note: Input image should be filtered or should be loaded as grey

In global thresholding, we used an arbitrary chosen value as a threshold. In contrast, Otsu's method avoids having to choose a value and determines it automatically. Consider an image with only two distinct image values (bimodal image), where the histogram would only consist of two peaks. A good threshold … See more 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 … See more 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, adaptive thresholding can help.
