It's been a long time coming, but with the recent upgrades and layout changes I was finally able to bring back our popular DME Resources Map.

The DME Resources Map allows members to add markers for their agency or organizational resources related to forensic multimedia analysis. Visitors and members are then able to easily locate nearby DME resources that may be able to assist them.

Two new large format printers from Canon are ready for their big close-up at the Wedding & Portrait Photographer International (WPPI) Convention in Las Vegas next week.

The 24-inch and 44-inch models of Canon's imagePrograf line of large page printers have a new 8-color system (cyan, magenta, yellow, black, matte black, photo cyan, photo magenta and gray) and Canon's "Lucia Ex" ink-set, which can achieve greater details in shadows, deeper black density, and improved scratch resistance.

SSD enthusiasts know all about SLC, MLC, and TLC, but there are some new acronyms in SSD town: V-NAND and CTF. Samsung announced in a press release last night that it has begun mass production of "3D Vertical NAND," a type of flash that it claims overcomes the existing limits on the design and production of existing NAND types.

Moments ago, I completed several updates and upgrades to the Media-Geek community. While most of them where behind the scenes type of stuff, there were some new features introduced that members might find interesting, such as:

  • Photo and video support for groups - Group members can now upload photos and videos to be shared among fellow group members.
  • Photo Tagging - Users can now tag their friends in any of their photos
  • Community Content Sharing - Users can now easily share their videos, photos, group bulletins and discussions with all the major social bookmarking services (digg, delicious, Stumbleupon, etc) as well as social networks like Facebook, Myspace, Bebo, LinkedIn, and more!
  • Friend Suggest - Users can instantly expand their network by adding friends with our 'Friend Suggest' tool
  • Wall Post Notifications - Get notified when someone posts a new message or responds to an old message on your wall.

Various layout issues and minor bugs were addressed as well during the upgrade process, but as with all Web sites it will always be a work in progress. If you stumble across a problem or have a questions/recommendation, as always, simply shoot me a note or post it to the member forums. Thanks for participating!

There ARE Non-square samples, and their shape IS NOT dependent on the # of scanning lines. There are also Non-Square picture elements in CCD and CMOS image sensors, but their electrical charge is never converted to digital in an analog CCTV camera.

Back in the day there actually were Non-Square pixel-based displays, but they were only used for special applications and are not found in the wild today.

If you are aware of a standard that defines the shape of 480i (NTSC) or 576i (PAL) non-square samples differently than through the use of the luminance sampling frequencies, please bring that to my attention. Thank you.

One of the many reasons Cloud solutions are so attractive is because of the substantially lower capital investment costs to implement them, when compared to building your own solution. Many vendors are willing to give away equipment & services initially, knowing full well that once you're in their ecosystem they'll get their money back, tenfold. How can they be so confident? Well, generally because it'll cost far more than your agency can ever afford up front in order to leave their ecosystem/solution. That's their business model.

One of our members brought to my attention that the blog post form wouldn't allow you to save and publish your post.  Eventually, I found the reason and resolved it this morning.

You may have seen in a recent newsletter that we're cleaning up our database over the next few weeks.  If you missed that notice here's the skinny - we will be deleting all user accounts that have been inactive for more than 6 months.  If you have logged in within the last 6 months you're good to go; if not, you'll probably be deleted.  Any questions or concerns, as always, feel free to contact me.  Thanks for participating and have a great holiday weekend!

 

In support of LEVA member agency the Vancouver Police Department and the Integrated Riot Investigation Team (IRIT), LEVA announces the activation of the Forensic Video Analysis Response Team.

IRIT investigators are inundated with over 1600 hours of video depicting criminal acts that took place immediately following this summer's Stanely Cup hockey finals, including arson, looting, and serious assaults.

Between September 26th and October 9th over 40 LEVA Forensic Video Analysts will converge on the National Digital Multimedia Evidence Processing Lab at the University of Indianapolis to undertake the mass processing of DME.

For further information please feel free to contact LEVA President Blaine Davison via email at president@leva.org
