Imgproc.thresh_binary
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. The first argument is the source image, which should be a … Zobacz więcej 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. … Zobacz więcej 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. Here, … Zobacz więcej Witryna这两种标志是获取阈值的方法，并不是阈值的比较方法的标志，这两个标志可以和前面5种标志一起使用，例如“thresh_binary thresh_otsu”。前面5种标志在调用函数时都需要人为的设置阈值，如果对图像不了解设置的阈值不合理，会对处理后的效果造成严重的影响，这两个标志…
