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.

A method for using a camera on a mobile device to display brand information, comprising:
- receiving a request for brand-related information;
- obtaining an annotated map comprising physical characteristics and wireless signal parameter information;
- measuring wireless signal parameters;
- determining a rough location based at least in part on the measured wireless signal parameters and the annotated map;
- receiving a reference image feature data table based on the rough location of the mobile device, wherein 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.
A mobile device for providing location-based brand detection, comprising:
- an image capture module;
- a memory configured to store a reference image feature data table, wherein the reference image feature data table comprises at least one entity record including a plurality of logo image feature fields;
- a processor programmed to:
- measure wireless signal parameters;
- determine a rough location of the mobile device based on the wireless signal parameters;
