MATLAB: How can you transform a color x3uint8 image to uint8

colorimageuint8

 I have following color image 1152x2048x3 uint8. Is there any way to transform it to 1152x2048 uint8 while still keeping the colors ?

Best Answer

No, because for each pixel 2^(8+8+8) different colors are possible.

yellow = red == 255 & green == 255;

if you are using a uint8 image or replace 255 with whatever the data maximum is otherwise.

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);
