HSV to RGB using entered values
显示 更早的评论
I have used the rgb2hsv and changed my rgb image to hsv, then asked the user to enter new h and s values .. now I want to create the new rgb image with these new h and s and v values, could anyone help me with it? how can I combine these hsv seprate values into one rgb image?

Assuming you original image is im:
hsv = rgb2hsv(im); % HSV version of original image
HSV = hsv; % HSV version of image we're modifying
HSV(:,:,1) = mod(hsv(:,:,1)+0.2,1); % Shift the hue component, this is not pretty...
HSV(:,:,2) = hsv(:,:,2).^.75; % Change the saturation
IM = hsv2rgb(HSV); % Convert back to RGB
subplot(1,2,1),imagesc(im) % display anf compare
subplot(1,2,2),imagesc(IM) % the 2 images
Obviously you'll haveto modify the H&S modification to what you want to achieve...

Why cant you use hsv2rgb? It's also not clear to me how you have your users entering new hue and saturation values - do you really expect them to give new parameters pixel-by-pixel, that would be a very large number of numbers to enter for anyone...
