I=imread('D:\canal images\df.jpg'); imtool(I);
I2=imcrop(I,[]);
subplot(1,2,1); imshow(I); title('Original Image');
subplot(1,2,2); imshow(I2); title('Cropped Image');

You need to specify the cropped region first try something like this:
I=imread('D:\canal images\df.jpg'); imtool(I);
I2=imcrop(I,[a b c d]);
subplot(1,2,1); imshow(I); title('Original Image');
subplot(1,2,2); imshow(I2); title('Cropped Image');
where 'a' and 'b' are the starting points 'c' and 'd' are the width and height in pixels.

a and b are where you want to start cropping your image, c and d are the dimensions you want you may want to try some values if you have only one image. It depends on what defines your cropped region. You can as well use the data cursor (next to the rotate tool) when you show your image it gives you the x and y coordinates of the pixels
