Object recognition
This is just the tip of the iceberg
•We’ve
talked about using pixel color as a feature
•Many
other features can be used:
–edges
–motion
(e.g., optical flow)
–object
size
–...
•Classical
object recognition techniques recover 3D information as well
–given
an image and a database of 3D models, determine which model(s)
appears in that image
–often
recover 3D pose of the object as well
–new
work (e.g., Linda Shapiro’s group at UW), seeks to recognize
3D objects (meshes) by training on 3D scan data
