Hi, I don't understand what is the meaning of this coding?
imshow(lab(:,:,1),[0 100])
why there is [0 100]? what is the meaning of that code?
I read the code from here https://www.mathworks.com/help/images/ref/rgb2lab.html

L*
Luminance or brightness of the image. Values are in the range [0, 100], where 0 specifies black and 100 specifies white. As L* increases, colors become brighter.
ok, i have found the asnwer why it is range [0 100]. It's noted at the document as well.
