Object and Scene Recognition Using Eigenimages

Abstract




The appearance
-
based approaches to computer vision problems have recently
received a renewed attention in the vision community due to their ability to dea
l with
combined effects of shape, reflectance properties, pose in the scene, and illumination
conditions.

Besides, appearance
-
based representations can be acquired through an automatic
learning phase which is not the case with traditional shape representat
ions.


The approach has led to a variety of successful applications, e.g., visual positioning
and tracking of robot manipulators, visual inspection, and human face recognition.


In this talk I will present the basic ideas of eigenspace methods for appe
arance
-
based
object recognition. Various methods for training and recognizing objects will be outlined.


I will also identify the major limitations of the approach and present algorithms which
alleviate the problems, leading to an object recognition syste
m which is applicable in
real world situations. Throughout the talk, all the concepts will be demonstrated on real
images.
