Project 5: [Auto]Stitching Photo Mosaics

Thomas Low

Overview

This project explores stitching images through homographies and projective warping.

Part 1: Image Warping and Mosaicing

This part generates image mosaics by registering, projective warping, resampling, and compositing photographs.

Recover Homographies

To find the transformation parameters between a pair of images, we can solve a linear system of equations from our correspondence points.

Conclusion

Panoramic pictures depend on homographies to stitch images together. Through this project, I learned that computing a homography can be simply done through a linear system of equations.
