"i write this code but it cannot run. help...!!"

If you get an error, give us the full text of the error message so we don't have to guess what the problem can be.

First problem with the code you show is that cameraman is mispelled. Whether or not that's why it cannot run is unknown.

Answer 1

[Walter Roberson]

Your code is assuming that camerman.tif is RGB without testing to see if that is true.

You can test it by looking at size() and ndims(), or by looking at the output of imfinfo()

Answer 2

[KALYAN ACHARJYA]

img = imread('cameraman.tiff'); % Read the image
[rows, colm, dim]=size(img);

Here rows and clom gives the number of rows and column in the image

Whereas dim give the dimention of the image. In adition, if you wish to extract the color plane- here it is

red_plane=img(:,:,1); % Red Channel
green_plane=img(:,:,2); % Green Channel
blue_plane=img(:,:,3); % Blue Channel

Hope it Helps!

it says "Index in position 3 exceeds array bounds (must not exceed 1)"
