[2005] Image Stitching algorithm for panorama application

I need to create an panorama app that stiches some small images into one big panoramic image.

I googled for an algorithm on image rendering, image merging ( the two parts of image stitching ) and all I got is math documentation and not a single line of code.

I usually dont ask for code but for documentation or maybe some links , but in this case the documentation is too math focused and it's at expert level.

Can anyone redirect me to an similar project ( with code ) or an documentation also with code please

Thank you
