I am studying the Imaging Processing Toolbox tutorial and under the 'Example 2 Advanced Topics' chapter, everything is fine until I get to 'Step 5: Adjust the Contrast in the Processed Image'. I get the following error;
??? Error using ==> imadjust>parseInputs at 212
IMADJUST(I) is only supported for 2-D grayscale images.
Error in ==> imadjust at 98
ma] = ...
when I enter I3=imadjust(I2);
Can someone please advise why this is?
I am trying to change the picture below into black and white and grayscale
What does this mean
