WebApr 7, 2024 · Binary thresholding is the process of converting image pixels to black or white given a threshold, in this case 127. Pixel values lower than the threshold are converted to 0 (black), and values greater than or equal to the threshold are converted to 255 (white). The image generated is a binary image with two pixel values. ‍ Webthreshold(Image, BinaryImage, 128, 255) 其中，第一个参数是输入灰度图像，第二个参数是输出的二值图像，第三个参数是阈值下限，第四个参数是阈值上限。该函数将大于或等于阈值的像素设置为白色（255），小于阈值的像素设置为黑色（0）。 2. 局部阈值处理：
