Hello.
I wanna centering an image (image 1 to image 2)
image 1 image 2
I got the image 1 from this code.
clear all
close all
%// read the video:
reader = VideoReader('lena_side.avi');
vid = {};
while hasFrame(reader)
vid{end+1} = im2single(readFrame(reader));
end
%// simple background estimation using mean:
bg = mean( cat(4, vid{:}), 4);
%// estimate foreground as deviation from estimated background:
fIdx = 40; %// do it for frame 43
fg1 = sum( abs( vid{fIdx} - bg ), 3 ) > 0.25;
figure;
subplot(141); imshow( bg );
subplot(142); imshow( fg1 );

Hi
The image is gray scale with one object and the object is present in the right half of the image, so the usual approch could be to find the centroid of the object and shift the centroid of the object to the center of new image. New image should be the image consisting of zeros with same size of previous image.
