The Golkonda Fort complex is spread over 7 km, in circumference.
Mostly in ruins, it still has many interesting
buildings and structures. We worked with a dataset of 5,500
images spread over the entire fort. For testing our app, we
identied 14 signicant structural buildings and collected
a set of 10-15 test queries at each of these scenes. These
query images (See Figure 7) were taken using low-end mobile
phones with resolution as low as 3 MP. We evaluate the
application's performance on these queries and achieve 96%
mean Annotation Accuracy (See Table 3). We also observe
the time taken for processing a query image on the mobile
device (See Table 2). The annotations for query frames are
retrieved and displayed on the screen of the mobile device in
an average time of 1.5 seconds. We analyse the feature data
storage and RAM usage on the mobile phone for our app on
Golkonda (See Table 4). Our app uses occupies
