   clc;
   I=imread('b2.bmp');
  figure(1),imshow(I);
   I=double(I);
   [M,N] = size(I);
%  blue_mask = repmat([1 0; 0 0], M/2, N/2);
%  green_mask = repmat([0 1; 1 0], M/2, N/2);
%  red_mask = repmat([0 0; 0 1], M/2, N/2);
%  
%  R=I.*red_mask;
%  G=I.*green_mask;
%  B=I.*blue_mask;
   B = I(1:2:end,1:2:end);
  G1 = I(1:2:end,2:2:end);
  G2 = I(2:2:end,1:2:end);
  R = I(2:2:end,2:2:end);
  G = (G1+G2)/2;
   figure(2), imagesc(R);
   figure(3), imagesc(G);
   figure(4), imagesc(B);
   final(:,:,1)=R;
   final(: ,:,2)=G;
   final(: ,:,3)=B;
   final=double(final);
   final=final*125/15;
   final=uint8(final);
%  imshow(final)
% I = imread('b2.bmp');
% J = demosaic(I,'bggr');
% imshow(I);
% figure, imshow(J);

Best Answer

The computations should be fairly easy.
You will have to find some kind of graphics library to do the figure() and imagesc() parts, as graphics is not part of C and cannot be implemented in standard C.
Reading BMP images is not part of the C language, but you should be able to find a third party library to do the reading for you, as that part can be implemented in standard C
