and i want to enhance the color just like this example image http://imageshack.us/f/843/97895457.jpg/
then i use this code
i = imread ('d:\wildlife\page-3.png');
x=imadjust (i,[],[],0.5);
figure, imshow(x);SE = strel ('square', 3);
j=imerode (x, SE);
figure,imshow(j);
and the result is still unoptimal, and the size become smaller http://imageshack.us/f/24/untitp.jpg/
is there any other way to enhance color of this image?
