the user needs to crop the image himself a/c to the coding u suggested...if a user wants to crop half or three fourth of the original image automatically wt wud b the changing then?

What code are you referring to?
Perhaps you should just start your own brand new thread.
Or maybe the following will answer your question.

% Read in standard MATLAB demo image.
grayImage = imread('cameraman.tif');
subplot(1,2, 1);
imshow(grayImage, []);
title('Original Grayscale Image');
set(gcf, 'Position', get(0,'Screensize')); % Maximize figure.

[rows columns numberOfColorBands] = size(grayImage);
height = int32(3/4 * rows);
croppedImage = imcrop(grayImage, [1 1 columns height]);
subplot(1,2, 2);
imshow(croppedImage, []);
title('Grayscale Image cropped at 3/4 the height of the original');
