GeoVid: Capturing More Information In A Video

Market Opportunity

With the proliferation of smartphones and tablets, we can now easily record and share videos wherever we are. While this is fantastic for capturing relevant information, it can cause a headache for individuals tasked with the unenviable duty of cataloguing, searching and managing these videos. This is especially so with community projects, where numerous videos have been recorded by different people, at different locations and over different times. 

 

The Technology

A team at the NUS School of Computing has developed GeoVid, a new way of managing videos, based on the additional geographic data available within the video. 

A video recorded with the innovative GeoVid app on a smartphone or tablet includes a wealth of data, beyond just the recorded field of view. Sensors within these mobile devices also record geographic information related to the scenes, such as latitude and longitude, direction and light levels. GeoVid is able to use this meta-data to create a better method for storing, indexing, searching, handling and presenting a large collection of videos. 

 

Applications and Advantages

GeoVid is ideal in situations requiring an efficient way to manage videos. The system was validated by the Columbia College Chicago, which used GeoVid to catalogue a large number of videos taken during President Obama’s second inauguration. 

GeoVid can also be used for security or surveillance applications. This is becoming more significant, due to the rise in popularity of in-car cameras capturing scenes on the road. For example, if there was a bank robbery in town, authorities could access video footage from various taxi companies. Using GeoVid, they can easily select all videos taken at the relevant place, at the right time, pointing in the right direction, and use this to find the license plate of the get-away car. 

As an application, GeoVid can be downloaded onto a user’s mobile devices (both Android and iOS devices). Using the GeoVid app, video recordings will store details such as GPS location and compass direction. Videos are then uploaded to the GeoVid search server, where users can make geo-referenced queries (such as “select all videos taken along Orchard Road”). Moving forward, the team is building in an authentication mechanism, so only approved users can upload and search videos. 

NUS has applied for a patent for this technology and is seeking partners or licensors to further develop this technology and bring it to market.
