MATLAB: HSV to RGB using entered values

hsv

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?

Best Answer

H=im3(:,:,1); S=im3(:,:,2); V=im3(:,:,3); I seprated the hsv values with these commands, now I want to change the hsv values and combine them into one rgb image

MATLAB: Increase RGB image saturation.

This is easier in HSV colorspace:

RGB = rand(100, 100, 3);
HSV = rgb2hsv(RGB);
% "20% more" saturation:
HSV(:, :, 2) = HSV(:, :, 2) * 1.2;
% or add:
% HSV(:, :, 2) = HSV(:, :, 2) + 0.2;
HSV(HSV > 1) = 1;  % Limit values
RGB = hsv2rgb(HSV);

MATLAB: How to create a white image

Try this to create a grayscale image:

whiteImage = 255 * ones(N, M, 'uint8');
imshow(whiteImage);

To create an RGB image, try this:

whiteImage = 255 * ones(480, 640, 3, 'uint8');
imshow(whiteImage);
