I'm cracking 50, and I can't even imagine "retiring". In addition to my dayjob (which is plenty rewarding) I also volunteer for FEMA, Skywarn, ARES, and ARRL. Also looking to get my EMT cert. If I sat around on some b

I hate the term "AI" (even though I am CTO of a company with "AI" in its name, but since we use machine learning/DCNNs in our systems, it’s very trendy). The problem with "AI" is the "intelligence&qu

I took five years of Spanish -- high school and university (I thought I'd since forgotten it, this was 30 years ago). A few years ago I found myself in Barcelona for a week. First day, I was completely lost. By the end of my stay I f

This is not a lenticular display. It's a stack of 45 independent transparent TFTs.

I'm CTO of a machine learning/computer vision company, and quite a bit of the team's work is "gluing libraries together" -- but even so, it's an intensely interesting, rapidly evolving field. Plus I get to pla

I'd say there's a competition problem in that there are too many very poorly made "me-too's" that aren't even worth the 30 bucks. The Yi's come pretty close quality-wise to GoPro, have excellent build qua

All and all a good intro tutorial that gets into some of the common professional use cases. On "constant bitrate" assumptions and some of the subsequent discussion here, ANY transform-and-entropy codec like VP9 or H264 will ALWAY

They have a Yi 4k+ kit with a waterproof action case, much like the GoPro Hero line does.

So, I wonder how many ad placements were made by these companies that specifically targeted experienced talent OVER 40 years of age? I'm going to guess a big, fat, zero.

I used to work for a smallish (<50 headcount) company that sold high-value software with a LOT of secret sauce in it (image processing algorithms) mostly to telco, wireless, and MSOs. The primary reason those folks wanted the source cod

It's an interesting conundrum (for my family at least). My father was very highly educated (Professor Emeritus of semiconductor physics/EE at a major University, you've likely heard of it). I started out putting a couple of

Well, articles like this don't "Upset Me", but I appreciate them nonetheless. In the end, it starts with awareness, but ends in full action. In the meantime, I find myself making conscious choices like "You know, inste

Well, all I can say as a former Continental Platinum (and later United 1K) is that the combination has resulted in the uttermost cesspool of service, fees, annoyances, and outright insults (thanks for stranding me overnight in Louisville KY

I fly a lot. The only time that has happened to me was when I was on a flight out of Atlanta after taking my crew to a gun range to shoot some auto's. I'm gonna guess the cordite burns on my shirt and residue on my hands probabl

I didn't mean to imply that there were cases where it would Never converge, just that the number of iterations is not a-priori fixed or predictable.

We were doing GPU-based 2D-3D conversion for HD and 4K and one of the intermediate steps required that we compute a DT (distance transform), and JFA was perfect for this. The DT was used along with a Hough transform (also real-time) to con

I was running this on (high end) GPUs back in 2011, in real-time (30fps), on 1920x1080 video textures. I can confirm that the clever recursion and performance of this is mind-boggling. Oh, and you get a distance transform out of it as an

Yep, it's all fun and games until your ASI goes haywire because of ice or a bug in your pitot tube, see https://en.wikipedia.org/wiki/Air_France_Flight_447#Final_re... However one thing I DO find clever about th

While their approach is clever, it is not guaranteed to converge in a fixed number of iterations. Author states that constrained Delaunay Triangulation is "slow and error-prone". I disagree -- I've implemented parallel and

Well, I for one find this pretty cool, especially the part where you can select the altitude. As a licensed remote pilot, this gives me a good idea of winds aloft at-a-glance without having to parse an entire full-briefing with all METARs,

For my job(s) the last 8 years or so, I've had a mix of on-site (10%), travel (40%) and work-from-home (the remainder). There have been very long stretches when I'm neither in the office, nor travelling to meet with customers, ho

I for one, would like to see a DSP book that focuses less on algorithms but rather on practical problem solving, such as memory bus limitations, red/write coalescing schemes, register optimizations, caching, and other optimization tech
