Significance of this work
• The extension to 3D objects was an important
contribution.
• Instead of using brute force search, the
authors observed that
All the views of a single object, when transformed into the
eigenvector space became points on a manifold in that space.
• Using this, they developed fast algorithms
to find the closest
object manifold to an unknown input
image.
• Recognition with
pose finding took less than a second.
