How to recombine a color image divided into blocks?

Dear sir, i used the following code to divide a color image into 4 blocks:

img4x4 = mat2cell( org_img, size(org_img,1)/2 * ones(1,2), size(org_img,2)/2 * ones(1,2), size(org_img,3) );

Kindly tell m e how to reconstruct original image from the 4 different blocks?

img2x2 = mat2cell( org_img, size(org_img,1)/2 * ones(1,2), size(org_img,2)/2 * ones(1,2), size(org_img,3) );

reconstructed = cell2mat(img2x2);
