Project 6A: Image Warping and Mosaicing

Rectifying

we 'rectify' an image by making it front-facing. This can be done by recovering the homography between the images by focusing on correspondence points. In my case, I picked out parts of my source images I kew were supposed to be squares and mapped them to 4 points forming a square.

Warping

Given 2 pictures, we can use correspondence points to recover a homography which can then be used to warp an image into the same perspective as the other

Summary

The power of homographies is so interesting. I never would have thought to re-angle any picture, or that I even had the cpability of doing so. The fact that we can accomplish this by playing around a bit with some linear algebra is pretty awesome.
