Camera-Inclusive Systems: Don't Forget To Employ Sufficient Security Stratagems

Adding one or several image sensors to a system, along with the necessary "muscle" to process the captured still and video frames, can notably enhance that system's capabilities and consequent appeal to potential customers. But then again, as editor-in-chief of the Embedded Vision Alliance, you'd expect me to harbor such a belief, right? Keep in mind, though, that along with containing cameras, many (most? all?) of these systems offer network connectivity; wired, Wi-Fi, cellular, etc.

Embedded Vision: Assisting Those With Vision Limitations

Speaking of Apple's attempt to compensate for people's imperfections, the last paragraph of my previous writeup: Parziale also notes that the feature is optimized for the visually impaired thanks to VoiceOver in OS X. “VoiceOver helps positioning the card in front of the camera and the very fast image processing algorithm generates very quickly the result,” according to Parziale. “The user experience is amazing.”

Embedded Vision: Assisting Those With Patience Limitations

Back in mid-December, I discussed the barcode as a pioneering computer-now-embedded vision application, in the context of reporting the death of its co-inventor, N. Joseph Woodland. As such, a related (and more advanced) OCR (optical character recognition) innovation from Apple that came out around the same time also caught my eye.

Image Processing And Computer Vision In Boston: Speaking Is A Desired Option

Last September, I told you about two upcoming meetings of the then-embryonic Boston Image Processing and Computer Vision Group (BIPCVG).

Panorama Multi-Image Stitching: Clever Software Simplifies And Optimizes Capturing

Earlier this month, BDTI senior software engineer Eric Gregori and I delivered a technology trends presentation on embedded vision in mobile electronics devices at the Embedded Vision Alliance Member Summit, the video of which is currently being edited and I hope to publish soon here on the site. One of the key application areas that we discussed in depth is computational photography, which Wikipedia defines as:

Post-Capture Selective Focus: A Video-Capable DSLR Lets You Put The Concept To The Test

Interested in trying out plenoptic light field camera technology, but don't have access to a Lytro camera (or for that matter, a Toshiba sensor prototype)?

Post-Capture Selective Focus: Toshiba's Prototype Puts Lytro On Notice

Plenoptic camera technology, most commonly known nowadays by virtue of Lytro's ongoing promotion of the concept (and sales of the first-generation implementation), has received primary mainstream attention to date because the light field-based approach allows for post-capture selective focus on particular depth regions of an image.

The Humble, Pervasive Barcode: A Computer Vision Pioneer's Memorial Ode

Late last month, I shared the news of the death of Bryce Bayer, an Eastman Kodak scientist whose filter array breakthrough nearly 40 years ago is now in widespread use, enabling inherently monochrome CCDs and CMOS image sensors to capture full-spectrum color information.

Embedded Vision Is For The Birds...Literally

If you haven't yet viewed the video of Ken Lee's (VanGogh Imaging) presentation at September's Embedded Vision Summit, I commend it to your perusal. Lee begins with a quite hilarious story about an on-site audition he did of one of the first implementations of the company's products...running on automated inspection equipment at a hog farm, and used to monitor animal health.

Lytro: The Plenoptic Camera's Feature Set Continues To Grow

Lytro's light ray-based plenoptic camera technology, which enables post-capture selective focus on any particular depth region of an image, has received periodic mention on this site. Back in October of last year, for example, I covered the cameras' initial unveiling.
