%Breaking out in rgb components and equalizing messes with the color
%relations of hues,saturation etc. The effect can be seen by comparing the 
%grayscaled images of original and the rgb_equalised image.

%The rgb image seem to have a distorted mix of black and white proportion.
%In the original, however the effect is smoothened.
