This project mainly explores the principle of panorama that we use in our iphones! The whole practice builds on the idea that 3D projection can be simulated by 2D projective transformation if the projection center is fixed or the captured object is a planar surface. We can find the homography H just using as few as 4 pairs of corresponding points, and then the whole image can be projected into a new plane.

A great tool that makes everything automatic and easy is Harris Corner Algorithm. By finding all interesting  points and narrowing them down to more significant points, and then pairing points in 2 images up using LSE between patches around points,  we can produce corresponding points automatically with even smaller error compared to manual work.
