For gray image, we use the commands like adapthisteq, imadjust... How to increase the intensity for the color image.
Direct link to this answer:
Convert to hsv color space with rgb2hsv(). Then do those same things on the v channel, then transform back to rgb color space with hsv2rgb().

when i run the code, i am getting an error as 3 D images. Does my procedure follows your reply or i gone to a wrong approach
I have a doubt on your reply...can you explain me little bit brief about the line...do those same things on the v channel indicates... Exactly it indicates what?
take a look at http://en.wikipedia.org/wiki/HSL_and_HSV
HSV is a colorspace like rgb , you have three channel , insted of R, G and B, you have H, S and V,
a possibility is also to transform to gray scale
Your v is the full 3D image with all the h, s, and v channels. Do this:
hsvImage = rgb2hsv(rgbImage);
% Extract individual color channels.
hChannel = hsvImage(:, :, 1);
sChannel = hsvImage(:, :, 2);
vChannel = hsvImage(:, :, 3);
% Do stuff to the v channel.
% Then, after that recombine the new v channel
% with the old, original h and s channels.
hsvImage2 = cat(3, hChannel, sChannel, vChannel);
% Convert back to rgb.
rgbImage2 = hsv2rgb(hsvImage2);
Thanks Image Analyst.. Now, I got your point..
