Given that we calculate the homography matrix (3x3 in size) between two images--how can we blend two images in a panorama?
For example, look at this panorama w/o blending. How do we get rid of the seam between images using alpha blending or some other method?
Do you mean Blending ?
you can start with linear Blending or you can do more little complicated but
elegant by using laplacian Blending

also this question might help How to merge two images in opencv?
of course you can use the opencv stitcher which will do everything for you instead starting from the images
