Not sure what you mean by that. But there are several possibilities. You could convert the image to hsv color space with rgb2hsv, then use imadjust on the v channel, and convert back to RGB with hsv2rgb.
Or you could do the same thing on the s channel to make the colors more vivid.
Or you could use imfilter on the v channel to enhance edges.
How about doing it all over with adapthisteq() or imadjust()? If you want just the box, then you're going to have to extract it, enhance the contrast with something like imadjust() and then write it back - at least that's one way.
