Done with the server side of detecting the seed landmarks. An approach similar to the one mentioned in the Unloc paper implemented in getSeedLandmarks.m... Now working on the phone app to allow the users to annotate with these initial landmarks and their location. This strictly speaking has to be done by one user initially [ like the owner of the mall]. But subsequent users will be given this option also. Inducting these user annotated landmarks as actual landmarks will be up to the owner to decide.
