Project 5A: Image Warping and Mosaicing
Shooting and Digitizing Images
I decided to try to mosaic two images from my backyard. They are shown below.
Original Images
Recovering homographies and warping images
I recovered the homographies of the images and warped the first image to the second image. The correspondencies and warping are shown below.

Warping and Padding
Image Rectification
Double checked my warping function by ensuring it could rectify frontal images. The results are below.

Creating a mosaic
Using the results from above, in the creating homography and warping and padding section, I was able to create a blended mosaic.
Rectified Images
Learnings
My biggest learnings from this project were regarding the homographies and warping steps. Learning how to find a homography from least squares was really interesting. As was the process of recovering the new image coordinates from the homography.
