Abstract

Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for updating points of interest (POIs), such as for use in or with a mobile communication device, for example.

First claim

1 . A method comprising, at a computing platform:
receiving messages transmitted by mobile devices, said messages comprising digital media captured at said mobile devices while said mobile devices are located in a venue; determining a number of matches for one or more points of interest (POIs) at said venue based, at least in part, on said digital media and visual attributes of one or more images associated with said one or more POIs; and determining a presence or an absence of said one or more POIs at said venue based, at least in part, on said number of matches over a period of time.

2 . The method of claim 1 , wherein said one or more POIs comprise one or more POIs expected to be located in or visible from said venue.

3 . The method of claim 1 , wherein said determining said presence or said absence of said one or more POIs further comprises determining that at least one of said one or more POIs is no longer present in or visible from said venue in response to a decrease in said number of matches for said one or more POIs at said venue over said time period.

4 . The method of claim 3 , and further comprising updating POI data based, at least in part, on said determining that said at least one of said one or more POIs is no longer present in or visible from said venue.

5 . The method of claim 4 , wherein said updating said POI data comprises removing said visual attributes of said at least one of said one or more POIs from a database.

6 . The method of claim 1 , wherein said determining said presence or said absence of said one or more POIs further comprises:
estimating a location of at least one object of a digital image matching at least one of said one or more images based, at least in part, on a location tag in a received message comprising said digital image matching at least one of said one or more images; and determining a new POI in said venue based, at least in part, on said location tag and said at least one of said one or more images.

7 . The method of claim 6 , wherein said determining said new POI in said venue further comprises determining that said new POI has replaced an existing POI based, at least in part, on a comparison of said location tag with a location of said existing POI and a decrease in said number of matches for said one or more POIs at said venue over said time period.

8 . An apparatus comprising:
means for receiving messages transmitted by mobile devices, said messages comprising digital media captured at said mobile devices while said mobile devices are located in a venue; means for determining a number of matches for one or more POIs at said venue based, at least in part, on said digital media and visual attributes of one or more images associated with said one or more POIs; and means for determining a presence or an absence of said one or more POIs at said venue based, at least in part, on said number of matches over a period of time.

9 . The apparatus of claim 8 , wherein said one or more POIs comprise one or more POIs expected to be located in or visible from said venue.

10 . The apparatus of claim 8 , wherein said means for determining said presence or said absence of said one or more POIs further comprise means for determining that at least one of said one or more POIs is no longer present in or visible from said venue in response to a decrease in said number of matches for said one or more POIs at said venue over said time period.

11 . The apparatus of claim 10 , and further comprising means for updating POI data based, at least in part, on said determining that said at least one of said one or more POIs is no longer present in or visible from said venue.

12 . The apparatus of claim 11 , wherein said means for updating said POI data comprises means for removing said visual attributes of said at least one of said one or more POIs from a database.

13 . The apparatus of claim 12 , wherein said database comprises an image database for said venue having: said one or more images of said one or more POIs; visual features of said one or more POIs; or any combination thereof.

14 . The apparatus of claim 8 , wherein said means for determining said presence or said absence of said one or more POIs further comprise:
means for estimating a location of at least one object of a digital image matching at least one of said one or more images based, at least in part, on a location tag in a received message comprising said digital image matching at least one of said one or more images; and means for determining a new POI in said venue based, at least in part, on said location tag and said at least one of said one or more images.

15 . The apparatus of claim 14 , and further comprising means for obtaining said visual attributes of said one or more images from a comprehensive image database that includes one or more logos associated with a good or service or indicative of a source of said good or said service.

16 . The apparatus of claim 14 , wherein said means for determining said new POI in said venue further comprise means for determining that said new POI has replaced an existing POI based, at least in part, on a comparison of said location tag with a location of said existing POI and a decrease in said number of matches for said one or more POIs at said venue over said time period.

17 . The apparatus of claim 14 , wherein said location tag indicates: an estimated location of at least one of said mobile devices at a time said at least one object of said digital image was captured; an estimated location of said at least one object in said venue; or any combination thereof.

18 . The apparatus of claim 14 , and further comprising means for updating POI data based, at least in part, on said determining said new POI in said venue.

19 . The apparatus of claim 18 , wherein said means for updating said POI data comprise: means for including a name of said new POI in an image database for said venue; means for including said visual attributes of said new POI in an image database for said venue; means for replacing an existing POI with said new POI in an image database for said venue; or any combination thereof.

20 . An apparatus comprising:
a wireless transceiver to:
receive messages transmitted by mobile devices, said messages comprising digital media captured at said mobile devices while said mobile devices are located in a venue; and
at least one processer coupled to a memory and to said wireless transceiver to:
determine a number of matches for one or more POIs at said venue based, at least in part, on said digital media and visual attributes of one or more images associated with said one or more POIs; and
determine a presence or an absence of said one or more POIs at said venue based, at least in part, on said number of matches over a period of time.
