Crunching Video Intelligence With NVIDIA GPUs

Posted: 03 Nov 2011 10:00 AM PDT

Intelligence analysts are helping to protect vital national security interests at home and abroad by harnessing  NVIDIA GPUs and Intergraph's GeoMedia Motion Video Analyst software.

Getting accurate, timely intelligence has always been difficult for security analysts. Even the best intelligence is worthless if it can't be analyzed quickly and pushed out to the front lines in time to prevent the next attack or respond decisively to critical events.

Fortunately, we have access to plenty of solid intelligence today – too much of it in fact. As Lt. Gen. David A. Deptula, U.S. Air Force deputy chief of staff for intelligence, surveillance and reconnaissance, has put it: "We're going to find ourselves, in the not too distant future, swimming in sensors and drowning in data."

That future is now.

Today, the challenge has shifted from data gathering to data analysis. Video intelligence poses the biggest problem. It has exploded in sheer volume and frequency, and at higher and higher resolutions – ultimately requiring massive computing power to process.

Take drones, which are used by the military to gather valuable video intelligence from hot spots around the globe. The frequency and size of incoming video streams they produce is simply too much for analysts to handle.

Enter Intergraph's Motion Video Analyst Professional software. It allows analysts to more efficiently evaluate and act on full-motion video from drones, as well as other sources. The software stitches together thousands of individual video frames and corrects for distortions caused by taking photos from varying elevations – the result is referred to as an "ortho-mosaic" image. This image can then be combined with other geographically accurate data (e.g., aerial photos, satellite imagery, or geospatial data). This is a tremendously intense computing problem best-suited for the parallel processing capabilities of NVIDIA GPUs. The result is much quicker turnaround from acquiring the raw video to taking decisive action.

There's no doubt that the use of video and imaging data will be a large and increasingly important tool for national intelligence in the future. The evolution of intelligent GPU-accelerated technologies will give security professionals scores of powerful new tools to quickly gather, analyze and act upon intelligence in any form.

This should help us all sleep just a little bit easier at night.

We’re Listening: NVIDIA’s Social Media Command Center

Posted: 02 Nov 2011 03:37 PM PDT

Fans are NVIDIA's life blood. They're why we come into work. They're why we innovate amazing products. And they're why we put on events like last month's GeForce LAN 6 on the USS Hornet aircraft carrier.

It's vital for us to know what fans are saying – so we can understand how we're doing and integrate feedback into our products.

Social media provides a great way for us to listen to what's getting said.

Enter the Social Media Command Center:

This is our official social media-monitoring hub, and how we stay plugged into the social web. It also serves as a training center to help NVIDIAns participate in social conversations, using apps like TweetDeck and Spredfast.

It also happens to be where I get to work every day, keeping an eye on fans' comments. I take all their feedback and deliver it to the right people here, whether the comments are good, bad or just for fun.

The command center boasts eight 22-inch Samsung monitors on a custom wall-mount, powered by two Quadro 450 professional graphics cards. The wall of monitors makes for an impressive display that attracts lots of visitors, including our top execs.  We use watt-stoppers to conserve energy use in the Social Media Command Center when it's not in use.

Whenever we launch a new driver or product, I stay posted at my station to monitor social media traffic, as do others in the customer care and driver teams. When fans have issues, we identify NVIDIA employees who are best suited to help, and mobilize to resolve these issues as quickly as possible. When fans indicate that they like certain features, we try to focus on those in future releases.

The Social Media Command Center allows NVIDIA to  address fan feedback quickly. While we may not be able to answer each tweet or forum post directly, fans should know that we're reading all your comments and we definitely care.

If you want to join the conversation with NVIDIA here are some resources to help:

  • For technical issues visit nvidia.com/page/support.html
  • To become a member of one of our community sites on Facebook or to talk to us on Twitter, check out our "find us online" page. It's a directory of NVIDIA profiles across product families and regional accounts.
  • To join our forums and  talk to other NVIDIA fans, visit forums.nvidia.com
