MATLAB: Image stitching

canvasimage stitchingpanaroma

hii..for image sitching,i found out the registration parameters(translational and rotational)using phase correlation…the next step is to create a canvas of the 2 images,which i am unable to do..please any one give me any idea..thanx in advance..

The approach I take is to pre-allocate the final image, then just "drop in" the image data in the appropriate locations. This works for regular tiling, including translation. I've never had occasion to apply a rotation, but hopefully this is applicable. Perhaps use imrotate on the tiles before trying to add...

fullmask(ttop : tbottom , tleft : tright , :) = imadd(fullmask(ttop : tbottom , tleft : tright , :), temp_img) ;

Where fullmask is your final image, and ttop, tbottom, tleft, and tright are the coordinate extremes of the image to be added. Such that if you had a 100x100 pixel image to add in the upper left corner, ttop = 1, tbottom = 101, etc.

MATLAB: How to add image ‘x’ to even frames and one image ‘y’ to odd frames

Hi,

According to your description there doesn't seem any need for nested loops. Try making use of the following code:

outputVideo= VideoWriter('newfile.avi');
open(outputVideo);
for ii = 1: 2: length (imageNames)
   kk=ii+1;
        img1 = im2single (imread (fullfile (workingDir, 'images', imageNames {ii})));
        image_2 = im2single (img1 + output_cross_alfa);
        img2 = im2single (imread (fullfile (workingDir, 'images', imageNames {kk})));
        image_1 = im2single (img2 + output_cross_Nalfa);
        output = image_1;
        writeVideo (outputVideo, output);
        output = image_2;
        writeVideo (outputVideo, output);
end
close(outputVideo);

Hope it helps.

MATLAB: How to stop the iteration Tn(j,i)=Tn+1(j,i)

Replace your for loop by:

tol = 10^-6; % Or whatever is appropriate
err = 1;
 while err>tol
     Told = T;
     for i=2:nx-1
        for j=2:ny-1
            T(j,i)=((T(j-1,i)+T(j+1,i)+T(j,i-1)+T(j,i+1))/4);            
        end   
     end
    err = max(max(abs(T - Told)));
 end
