Introduction

  • Rock Art documents ancient cultures around

the world.

  • Many digital libraries collect images and

descriptions of this rock art.

  • However, there is no link between archive

and art when a visitor visits an actual site.

The Goal

  • A visitor to the site takes a picture with a phone

camera.

  • An application on the phone then tells her

exactly what she is looking at. ○ Maybe with a list of probable candidates, like a search engine.

  • Create a link from the archive to the physical to

support education.

Methodology

  • Use feature extraction algorithms to

convert images to key attributes:

○ SIFT, SURF, FAST

  • Use information retrieval algorithms to

perform a fast search operation on a mobile device.

Current Status

  • SIFT works well to find key attributes on a

phone.

  • Search indexing algorithms are being
  • ptimized.
  • We can already find the correct image within

a specific site.

  • ...but we can do better!

Future Work

  • Formal evaluation of application on mobile

phone.

  • Testing and possible deployment in the

field, in collaboration with Department of Archaeology at UCT.
