  1. Introduction to Computer Vision Michael J. Black Oct 2004 Object Recognition CS143 Intro to Computer Vision

  2. Goals Last class: * Finished PCA. Today * Object Recognition, Light, Cameras. Wednesday * light and cameras wrap-up and DFFS (Alex) CS143 Intro to Computer Vision

  3. Object Recognition In Assignment 2 you learn a model of mouths. - purely based on appearance - aligned data - one class (with some variation) - un-occluded - standard viewpoint CS143 Intro to Computer Vision

  15. Parts Learn parts from examples. Find interesting points (structure tensor), find similar ones, use PCA to model them. From: Rob Fergus http://www.robots.ox.ac.uk/%7Efergus/ CS143 Intro to Computer Vision

  16. Shape Given a “vocabulary” of parts, learn a model of their spatial relationships From: Rob Fergus http://www.robots.ox.ac.uk/%7Efergus/ CS143 Intro to Computer Vision
