MATLAB: How to write a range of values from minimum to maximum in black and white image display

Question

i write:

figure; 
imshow(image);
caxis;
[min(min(image)); max(max(image)))]; 
colorbar %black&white

and the Error is: Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched

delimiters.

Answer 1

I = imread(image) ;   % give your image name 
imshow(I) ; 
I0 = min(I(:)) ;  % min value
I1 = max(I(:)) ;  % max value
