Embedded Vision Insights: April 10, 2014 Edition

Dear Colleague,

I’m pleased to report that videos of three interesting presentations from the recent Embedded Vision Alliance Member Meeting are now available:

• "Who Watches the Machines Watching You? Regulating Privacy in the Era of Machines That See" by Brian Wassom, Partner and Chair of the Social, Mobile, and Emerging Media Practice Group at Honigman Miller Schwartz and Cohn LLP
• "Recent Developments in Khronos Standards for Embedded Vision" by Neil Trevett, President of Khronos, and
• "Forecasting Consumer Adoption of Embedded Vision in Mobile Devices in 2014" by John Feland, PhD, CEO of Argus Insights.

Looking forward, we’ve just published the full technical program for the Embedded Vision Summit West, a technical educational forum for engineers interested in incorporating visual intelligence into electronic systems and software.  The Summit take place on May 29 in Santa Clara, California.  Online registration for the Embedded Vision Summit West is now available. Last year's Summit sold out, so I encourage you to register right away before the attendance slots are filled.

And as a reminder, two in-depth technical workshops will also take place the prior day. The first, from Alliance founding member BDTI, is entitled "Implementing Computer Vision and Embedded Vision: A Technical Introduction". It will provide a practical tutorial on processors, sensors, algorithms, and development techniques for vision-based application and system design, including OpenCV and OpenCL. The second is co-presented by BDTI and fellow Alliance members Analog Devices and Avnet Electronics. It will explore hardware and software for image processing and video analytics in a hands-on fashion, featuring the Avnet/Analog Devices Embedded Vision Starter Kit.

In addition to the latest content on the Alliance website, I also encourage you to head to EE Journal and peruse the recently published article "Augmented Reality: A Compelling Mobile Embedded Vision Opportunity", authored by the Alliance and member companies CogniVue, SoftKinetic and videantis. Thanks as always for your support of the Embedded Vision Alliance, and for your interest in and contributions to embedded vision technologies, products and applications. And please don't hesitate to let me know how the Alliance can better service your needs.

Lucas-Kanade Feature Tracking
Jeff Bier, founder of the Embedded Vision Alliance, interviews Goksel Dedeoglu, Founder and Lab Director of PercepTonic, and former Manager of Embedded Vision R&D at Texas Instruments. They begin with a hands-on demonstration of real-time Lucas-Kanade tracking using TI's Vision Library VLIB on the C6678 Keystone DSP, wherein thousands of Harris corner features are detected and tracked in 1080p HD resolution images at 15 frames per second. Jeff and Goksel touch upon various aspects of visual tracking: what are good features to track in images, how to track them, and how tracking can enable embedded vision applications.

Embedded Vision Summit Technical Presentation: "Porting Applications to High-Performance Imaging DSPs," Chris Rowan, Cadence
Chris Rowen, Fellow at Cadence and Founder of Tensilica, presents the "Porting Applications to High-Performance Imaging DSPs" tutorial within the "Developing Vision Software, Accelerators and Systems" technical session at the April 2013 Embedded Vision Summit. Rowen discusses the challenges of porting and tuning applications to a high-performance imaging DSP. An imaging-specific DSP can make a huge difference in the performance of computationally intensive algorithms. But you can’t expect to just quickly port those algorithms –you need to tune them. A Bilateral Filter example is given where a 123x speedup was first determined, but after tuning the speedup increased to 300x. Software development environments are also discussed.

Vehicle Entrance Control Market Looks to Adopt Automatic License Plate Recognition
TThe growing adoption of automatic license plate recognition (ALPR) technology is having an adverse impact on the vehicle entrance control industry, specifically the vehicle barrier and off-street parking systems markets. According to IHS, the presence of ALPR technology is increasing the most for toll ways and off-street parking garages, which is negatively impacting the growth of vehicle barriers. In ALPR mature markets such as the Americas where the adoption of the technology is prevalent, highway/toll barrier revenues are projected to decline by 16.1% from 2013 to 2017. More

Video Door Phone Market Opens Up to Fast Growth
AThe $1.8 billion global door phone market is transitioning from audio to video technology, with video set to grow and account for 50 percent of unit shipments in 2017, according to a new report entitled “The World Market for Audio and Video Door Phones” from IHS. Worldwide unit shipments of video door phones are forecast to grow by 7.5 percent during the next five years, with several technological advances and benefits helping to drive the transition from audio to video door phones. These trends include increased integration with building automation, a transition toward “hands off” indoor units along with larger 7-inch screen sizes, and an increase in the use of network systems and megapixel cameras.
