HOW CAN I ADD RBG color at a given point say x(2,, 7) and generate the wavelenght?

let say this is my code f=imread('/tmp/marbles.jpg'); f=uint8(f); %need to convert back to uint8 to show picture

%Split into RGB Channels f_red = f(:,:,1); f_green = f(:,:,2); f_blue = f(:,:,3); the values of red , green and bleu are sorted but at a particular point they all interset e.g (2 6). what is the wavelenth at position (2,6). please can someone help me to generate the code if possible?

Hi Jean Paul,

Could you clarify what you mean by three vector of color values "intersecting"? And what do you mean by the "wavelength"? Are you trying to convert the RGB value to light wavelength?

[Jean Paul Noukimi]

Yes from RGB To wavelength. Or from rgb To spectrum
