In this paper, we demonstrate a computer vision application
on mobile phones. One can take a picture at a heritage
site/monument and obtain associated annotations on
a mid-end mobile phone instantly. This does not require any
communication of images or features with a remote server,
and all the necessary computations take place on the phone
itself. We demonstrate the app on two Indian heritage sites:
Golkonda Fort and Hampi Temples. Underlying our application,
we have a Bag of visualWords (BoW) image retrieval
system, and an annotated database of images.
