Why can’t we use GPS everywhere? Urban canyons Indoor navigation 1. Introduction - 2/20
3
What we are trying to do Camera Inertial Altimeter, Compass +/- GPS = Accuracy + Location + Maps + 1. Introduction – 3/20

Object Category Recognition 3. Object Detection & Recognition – 9/20
10
Classes of Objects vs. Instances 2 instances of an individual object (space shuttle) 2 instances of an object face class 2 instances of an object motorcycle class 3. Object Detection & Recognition – 10/20
11
Visual vs. Functional classes There is a wide variation in the appearance of objects that are categorized by function. We focus only on categories related by some visual consistency only! 3. Object Detection & Recognition – 11/20
12
Challenges changes of viewpoint transformation (translation, rotation, scaling, affine), out-of-plane (foreshortening) illumination differences background clutter occlusion intra-class variation 3. Object Detection & Recognition – 12/20
