How can we find correspondences and use them for robust estimation?
Lectures
Trym's first three lectures this week have not yet been transitioned to English. Let him know if anyone would like to discuss these lectures in English before Friday!

Lab: Image mosaics from feature matching
In this lab we will experiment with feature detection and matching to extract point correspondences between two images. We will then use these correspondences to estimate a homography between the images, which will enable us to create a live video mosaic!
