Abstract

Techniques for determining brand information and refining a position of a mobile device are described herein. An example of a method for displaying branding information on a mobile device includes receiving a reference image feature data table based on a rough location of the mobile device, such that the reference image feature data table includes a collection of entity records and wherein each entity record includes a plurality of logo image feature fields, obtaining an image including a displayed logo, utilizing an image recognition process and the reference image feature data table on the image to determine a recognized logo, and displaying brand information based on the recognized logo.

First claim

What is claimed is:

1 . A method of providing reference image feature data to a mobile device, comprising:
obtaining a rough location area of the mobile device; selecting a relevant points of interest list based on the rough location area of the mobile device; refining the rough location area of the mobile device if the relevant points of interest list is greater than a threshold; building a reference image feature data table if the relevant points of interest list is less than or equal to the threshold; and providing the reference image feature data table to the mobile device.

2 . The method of claim 1 wherein the reference image feature data table includes at least one entity and a plurality of logo image feature fields that are associated with the entity.

3 . The method of claim 2 wherein the reference image feature data table includes position information associated with each logo image feature.

4 . The method of claim 1 wherein refining the rough location area includes receiving a wireless signal information from the mobile device.

5 . The method of claim 4 wherein the wireless signal information includes Round Trip Time (RTT) data.

6 . An apparatus, comprising:
a memory; at least one processor coupled to the memory and configured to:
obtain a rough location area of a mobile device;
select a relevant points of interest list based on the rough location area of the mobile device;
refine the rough location area of the mobile device if the relevant points of interest list is greater than a threshold;
build a reference image feature data table if the relevant points of interest list is less than or equal to the threshold; and
provide the reference image feature data table to the mobile device.

7 . The apparatus of claim 6 wherein the reference image feature data table includes at least one entity and a plurality of logo image features that are associated with the entity.

8 . The apparatus of claim 7 wherein the reference image feature data table includes position information associated with each logo image feature.

9 . The apparatus of claim 6 wherein the at least one processor is further configured to receive a wireless signal information from the mobile device.

10 . The apparatus of claim 9 wherein the wireless signal information includes Round Trip Time (RTT) data.

11 . An apparatus for providing reference image feature data to a mobile device, comprising:
means for obtaining a rough location area of the mobile device; means for selecting a relevant points of interest list based on the rough location area of the mobile device; means for refining the rough location area of the mobile device if the relevant points of interest list is greater than a threshold; means for building a reference image feature data table if the relevant points of interest list is less than or equal to the threshold; and means for providing the reference image feature data table to the mobile device.

12 . The apparatus of claim 11 wherein the reference image feature data table includes at least one entity and a plurality of logo image features that are associated with the entity.

13 . The apparatus of claim 12 wherein the reference image feature data table includes position information associated with each logo image feature.

14 . The apparatus of claim 11 wherein the means for refining the rough location area includes means for receiving a wireless signal information from the mobile device.

15 . The apparatus of claim 14 wherein the wireless signal information includes Round Trip Time (RTT) data.
