create a panorama

Microsoft's Image Composite Editor can do that, but you have to download a software and run it only on windows platform. Someone has already build online application:http://www.dermandar.com/create.php.

By using the knowledge I have learned in CV class, I wrote a program in Matlab to create panoramas. It takes about two minute to combine five images, and each image is of size 5 megabits.

Now the program can be improved in several aspects:
1)The interest points detection correspondence matching process, which is very time expensive, is written in a sequential loop, I can try to use parallel computation.
2)Try to use downsampled image to estimate homography to save time.
3)Try to eliminate the artifact in boundaries of the image.
