请问imshow(I)与imshow(I,[])显示图像为什么不一样啊？
I 为一副图像，为double型，isind（I）=1；imshow（I）与imshow（I，[]）显示的图像有何区别啊，我想保存第二副图像，图质量不变且不能有白边，因为我要用这幅图像进行计算。不知道也没有办法解决。谢谢 看看imshow的helpimshow(I,) displays the grayscale image I, specifying the display range for I in . The value low (and any value less than low) displays as black; the value high (and any value greater than high) displays as white. Values in between are displayed as intermediate shades of gray, using the default number of gray levels. If you use an empty matrix ([]) for , imshow uses ; that is, the minimum value in I is displayed as black, and the maximum value is displayed as white.
