Thanks

img = imread('tes2.jpg');
HSV = rgb2hsv(img);

Something like (untested):

rgbImage = imread('tes2.jpg');
HSV = rgb2hsv(rgbImage);
hueValue = HSV(:,:,1);
saturationValue = HSV(:,:,2);
Value = HSV(:,:,3);
Value = adapthisteq(Value); % Or your own custom function.
% Put back together
HSV = cat(3, hueValue, saturationValue, Value);
rgbOutput = hsv2rgb(HSV);
