CS194 Project5: 
Image Warping and Mosaicing

Introduction

In this project, we are going to warp images shot from the same point but different directions and produce a mosaic. If we know several images are taken from the same camera center, or the images capture a planer surface, we can project them into a same plane and create a panorama. The mian steps include:

1. create input images which are taken from a fixed position (but may be different directions) or images from different positions but on a planar surface. Otherwise, if the images capture an uneven plane from different centers of camera, we can't project the images onto a same plane. 

2. Calculate homography matrix by manually selecting more than 3 corresponding points on adjacent images (warp to plane of one of the image) and front-view plane (warp to a third plane) and do Least-Square Regression.

3. Warp the image to new plane by transforming old coordinates to new coordinates by multiplying with homography matrix.

4. Blend images on a same plane to create a mosaic.
