Hello All.
I have been trying to replace the original R, G and B components of an RGB image by applying the attached equations in MATLAB.
I don't know the functions to use. I have tried applying different filters but the results I get are inaccurate.

Interesting.... After using which of the equations did you arrive at your result? I have been trying to get a similar result to yours using equation (4) but I couldn't. Can you please share the code you used?

Hello Muftahu Kabir,
Here is the code ...
clear all;
close all;
I = imread('1.jpg');
figure, imshow(I);
IR = I(:,:,1);
IG = I(:,:,2);
IB = I(:,:,3);
I4 = I;
I41Index = find((IG - ((IR+IB)/2) + 15) > 0);
I4(I41Index) = 0;
I42Index = find((IR - IB) > 20);
I4(I42Index) = 0;
I43Index = find((IG - IR) > 15);
I4(I43Index) = 0;
figure, imshow(I4);
I5 = I4;
delta = 50;
I51Index = find(I4 > (255 - delta));
I5(I51Index) = 0;
I52Index = find(I4 < delta);
I5(I52Index) = 0;
figure, imshow(I5);
I6 = I5;
I61Index = find(I5 > 0);
I6(I61Index) = 255;
I62Index = find(I5 == 0);
I6(I62Index) = 0;
figure, imshow(I6);
imwrite(I6, 'I6.jpg');
