Project 4A

Overview

In this project, we warp images to change the way they are viewed. Image warping is also able to create mosaics of images.

Part 1 Shooting the Images

The images I shot to be rectified are as follows:

The images I shot for the mosaic portion are as follows:

Part 2 Recover Homographies

The first step in warping images is to calculate homographies. This was done by using least squares through solving the following equation:

Part 3 Rectify Images

The following images are the results of warping and rectifying the box and floor images into a square coordinate system. This warps the point of view to be from top-down

Part 4 Blending into Mosaic

Unfortunately I wasn't able to debug this in time so here were my results of warping the left image of the building TO the center image of the building

I believe the issue is that I made corresponding points before padding. I belive I should have padded then chosen the corresponding points

What I learned

Although I did not finish, this was definitely a cool project. I learned how practical this warping tool could be in analyzing old iamges or artworks. Rectification of images is a powerful tool that can recover lots of information.
