What are experiences with Beagle Juice use with Beagle Bone Black and xM? Has anyone tested idle battery life or with workloads? Or Gumstix OMAP?

We are working on a project to baseline power consumption for a smart camera that can be configured for passive stereo vision or IR+visible multi-spectral. The design does most of the frame by...

What are some of the state-of-art and practice tools and methods for data center intrusion dectection?

I'm working on some new ideas for IDS (intrusion detection systems) and just curious if anyone can point me to what's being used today and considered for the future in terms of research. My...

Can semantic storage motivate a whole new useful class of applications and smarter storage devices?

The mapping between semantic data (e.g. file systems and namespaces, databases, object stores) and the devices that store the associated bytes and blocks that compose them has been one-way by...

Can anyone recommend off-the-shelf cameras for NIR, SWIR, LWIR and TIR infrared bands?

Our project is focused on FPGA acceleration of primitive convolutions and transforms associated with multi-spectral sensor fusion and while visible CCDs are plentiful and quite affordable, finding...

Why is computer vision and integration with 3D graphics to regenerate augmented reality not recognized as the most important next step in computing?

Human computer interaction is critical to the acceptance and advancement of computing as history has shown numerous times. In the early days with main frames, computer time was considered more...

Will graphics and computer vision become fused where graphics is forward rendering and computer vision the inverse?

Graphics renders 3D scenes from render lists and scene descriptions (a render language) and Computer Vision seems to be advancing to where one can imagine a camera and co-processor (like a GPU)...

Human vision research notes that there are at least 9 visual cues used to judge scene layout - has anyone attempted intelligent fusion of all 9?

"Perceiving layout and knowing distances: The integration, relative potency, and contextual use of different information about depth" by James E. Cutting and Peter M. Vishton, enumerates and...

Is there significant innovation and research value to the new H.265 standard compared to older H.264 (e.g. 3D extensions, new methods of encoding)?

I have not seen a good book yet describing the added value of the new standard and have not had access to read it yet, so just curious what opinions are and if the investment of time is warranted yet.

Are the active structured light methods the best solution to 3D sensing and should we still try to emulate natural passive human binocular vision?

RGB-D (depth maps using structured light projection) have become quite popular and a big advance for segmentation and recognition in computer vision, but typically have limited range (e.g. 1 to 5...

What is the best way to deal with H.264 latency? Small GoPs? I-frame only? I and P frame only? Use a different encoder?

We explored latency in H.264 transport for UAV/UAS and based on our analysis, much of the capture to display latency apparently comes from H.264 P and B frame reordering in a GoP, which requires...

Would a low-cost binocular camera with an FPGA co-processor for image transformation be of value to your research?

I'm leading a student team at CU-Boulder and U. Alaska Anchorage to explore building our own camera from the ground up to interface via the DE line of Altera FPGA boards to TI-OMAP and the Mobile...
