MATLAB: How to process the 400 matrices to get the true color image

colordigital image processingImage Processing ToolboxSymbolic Math Toolbox

Hi, Now I got four hundred matrices (2D) at each wavelength with spectrometer. The wavelength range is about 500-600nm. Now I want to combine these 400 matrices to get true color of my sample. Since in Matlab, true color image is get with RGB. So the wavelength should transfer to RGB, then combine the 400 matrices. Does anyone know how to realize it?

Thank you very much

MuPAD function (that has no direct MATLAB interface):

Windows tool, but includes some code that could be converted:

Now, the above talk about converting one wavelength to RGB. I am not sure how one would convert multiple wavelengths together.

You will need spectrumRGB() function available in this package: https://www.mathworks.com/matlabcentral/fileexchange/7021-spectral-and-xyz-color-functions?focused=5172034&tab=function to convert wavelength to RGB values. Download it and place it in MATLAB path, then run the following code

rgbValues = spectrumRGB(400:0.2:650); % go from 400 to 650 nm wavelength
image = repmat(rgbValues, 200, 1, 1); % 200 is the height of image in pixel
imshow(image)

MATLAB: I did some changes in red,green,blue channel of the image .Now when is am using cat function it is giving me full white image.This is not the output i want

You have white image because of format. Try

imshow(uint8(new_img));

your code can be shorter (no for loop needed)

image=imread('732_img_.png');
[m,n,~] = size(image);
Red=image(:,:,1);
Green=image(:,:,2);
Blue=image(:,:,3);
red_avg = mean(Red(:));
green_avg = mean(Green(:));
blue_avg = mean(Blue(:));
avg = mean(image(:));
disp(red_avg);
disp(green_avg);
disp(blue_avg);
disp(avg);
new_red = avg/red_avg*Red;
new_green = avg/green_avg*Green;
new_blue = avg/blue_avg*Blue;
new_img=cat(3,new_red,new_green,new_blue);
imshow([image new_img])
