Day 13

Today

    • Finish Intro to Computer Vision
    • Keypoints, descriptors, and descriptor matching (slides: ppt, pdf)
    • Pick project teams and tentative topics

For Next Time

    • Writeup your proposal for the computer vision project
    • Suggested Reading: pages 1-18 of the Structure from Motion Reading (posted on NB)

Keypoints, descriptors, and matching

As always, pull from upstream to get the latest changes:

$ git pull upstream master

Go into the directory ~/comprobo2014/exercises/keypoints_and_descriptors.

Execute the command:

$ python match_keypoints.py

This will launch a simple GUI that will let you experiment with various parameters of key point extraction / matching. Play around with the interface, see if you can make sense of some of the behavior of the algorithm by referencing back to the lecture slides. If you want, you can replace the images in the folder to use any two images of your choice.
