Kindly tell me why the original image is not coming with this code. The resulting image receive is yellowish in color,instead of being similar to the image Img_new

Img=imread(‘lena_color.tif’); Img_new=rgb2gray(img); Send=zeroes(size(Img_new); Receive= zeroes(size(Img_new); Mask= rand(size(Img_new); for i=1 :256 for j=1:256 Send(i,j)=xor( Img_new(i,j),mask(i,j)); End End

image(send); imshow(send);

for i=1 :256 for j=1:256 receive(i,j)=xor( send(i,j),mask(i,j)); End End

image(receive); imshow(receive);

plz help
