Imshow bw

Witryna该函数可以自动计算图像的阈值，并将图像二值化，语法格式为：T = graythresh(I);BW = imbinarize(I, T); 其中，I是要进行阈值分割的图像，T是计算得到的阈值，BW是二值化后的图像。需要注意的是，阈值的选择对分割结果有着较大的影响，应根据实际情况进行调 … WitrynaThe output binary image BW has values of 1 (white) for all %pixels in the input image with luminance greater than LEVEL and 0 (black) %for all other pixels. (Note that you specify LEVEL in the range [0,1], %regardless of the class of the input image.) %BW = IM2BW(I,LEVEL) converts the intensity image I to black and white.
