Witryna12 kwi 2024 · 对于参数thresholdType，我们可以有两种参数选择传入 1.ADAPTIVE_THRESH_GAUSSIAN_C, 这种取阈值的方式，是通过对一个区块的像素点的灰度值进行高斯加权，再加上或者减去常数C作为阈值，这个权数是通过每个像素到中点的距离通过高斯方程得到。 （这个算法相对复杂我后面会单独开一篇博客进行讲 … WitrynaImage segmentation is highly useful in defining objects and their boundaries. In this chapter we perform some basic thresholding operations on images. We use OpenCV function threshold. It can be found under Imgproc package. Its syntax is given below − Imgproc.threshold (source, destination, thresh , maxval , type);

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
