MATLAB: How to Reconstruct an Image using bit plane. I have already separated all the bit layers of the image using for loops and bitget

digital image processing

if true
  % code
endclc;
close all;
clear all;
I=imread('car.jpg');
Im=I(:,:,1);
figure
[r,c]=size(Im);
s=zeros(r,c,8);
for k= 1:8
  for i=1:r
      for j=1:c
          s(i,j,k)=bitget(Im(i,j),k);
      end
  end
end
subplot(3,3,1) MSB=s(:,:,8); imshow(MSB) title('8th Bit/MSB Layer ')
subplot(3,3,2) Bit7=s(:,:,7); imshow(Bit7) title('7th Bit Layer ')
subplot(3,3,3) Bit6=s(:,:,6); imshow(Bit6) title('6th Bit Layer ')
subplot(3,3,4) Bit5=s(:,:,5); imshow(Bit5) title('5th Bit Layer ')
subplot(3,3,5) Bit4=s(:,:,4); imshow(Bit4) title('4th Bit Layer ')
subplot(3,3,6) Bit3=s(:,:,3); imshow(Bit3) title('3rd Bit Layer ')
subplot(3,3,7) Bit2=s(:,:,2); imshow(Bit2) title('2nd Bit Layer ')
subplot(3,3,8) LSB=s(:,:,1); imshow(LSB) title('LSB Layer ')

Best Answer

Just multiply and add
uint8Image = uint8(LSB + 2*Bit2 + 4*Bit3  + 8*Bit4 + 16*Bit5 + 32*Bit6 + 64*Bit7 + 128*MSB);
