Great lecture thank you Jeff and Eric.

Iron

Thanks again for this great lecture.

Iron

Thank you Jeff, Eric, Ann

@Ann - very limited use of oss (legal issues, etc...)

Iron

@Ann - windows, linux, Unix (Solaris)

Iron

Great to have access to the recorded sessions

Iron

Missed the live lecture...

Iron

Windows, visual basic

Iron

I use both Windows and Linux on my workstation.  My product designs are almost always bare metal.

Iron

I use linux, build linux, and use lots of open source software.

Iron

Thanks Eric and Jeff. Very informative session

Iron

thank you sir for guiding me. It will be helpful in my project. I will be glad if you can do the same after I start working more on open CV.  Thanks again, great work.

Iron

Yesterday, Jeff pointed me to an application Eric has worked in, a dice counter using a dual-core processor from Analog Devices, I'd like to ask, was the two cores feature of the processor a key to the project? Also, if possible, did you use OpenCV for that application?

Early next year we are hopnig to publish a white paper describing the process of developing this demo.  It will appear on the Embedded Vision Alliance web site. For today I'll just point out that the ADI chip actually has three cores: two Blackfin CPU/DSP cores and one "PVP" coprocessor for vision tasks.

ok, Qt creator has other parts like linguist and designer, so I want to work in that with using of camera , so which of them should I use or you cant tell more about Qt?

 

Iron

Kind of levels the "multi-core" playing field, brings back an element of "portable". Haven't really played with it enough to judge it, but thought I'd mention it as YOU are much more likely to find good use for it.

Platinum

time to go. thanks all for a great week and see you next time.

Iron

I have installed Qt creator in linux and open CV library for linux from the website you suggested, how to install oepn CV library in Qt creator?

 

I do not use QT.  Check the OpenCV WiKi.  It has all kinds of great install guides that should be able to help you out.

Blogger

This seminar along with all the other Design New seminars has been great. Thanks.

Iron

Have you run into Halide yet?


The first time I had heard of this was on these chats.  I Googled it and it looks very interesting.

PTZ - controllable pan,tilt,zoom  for AI controlled object tracking,

Iron

Yesterday, Jeff pointed me to an application Eric has worked in, a dice counter using a dual-core processor from Analog Devices, I'd like to ask, was the two cores feature of the processor a key to the project? Also, if possible, did you use OpenCV for that application?

Iron

@Eric&Jeff,   Any recomendations on a low light PTZ camera to use with OpenCV ?

 

I am not familiar with PTZ cameras?    If they have DirectShow drivers, they should work with the Windows version of OpenCV.

 

Blogger

Thanks I will check it out

Iron

@Eric  Any of the 200 algorithms geared to provide trackibility feedback to a PTZ camera ?

Iron

 

Does OpenCV integrate with LabVIEW?


As far as I know, OpenCV is not officially supported by NI in LabView, but there are third-party tutorials and I believe even one third-party software package for this purpose.

 

 

 

Blogger

thanks good session, and good week.

Iron

@Eric: I remember your using the term "haar" features (as in "haarcascade") in the lecture, but didn't see it on the slides.  Is it an acronym, and if so, what for? 

Iron

I'd also like to recommend the discussion forums on the Embedded Vision Alliance website for ongoing questions such as the ones that have been asked this week:

http://www.embedded-vision.com/forums

Jeff, Eric and I all regularly monitor it, as do other BDTI engineers and (more generally) the site visitor/user community at large

@Eric - I notice some of these demos detect eyes well.

What is the best method to detect Eye(s) on the face ?

Iron

can you suggest me about algorithm to use webcam inbuilt to laptop or use another cameras connected through USB port ?

All the demos I talked about can be used with a USB camera or a in laptop camera, as long as you have the camera drivers.

 

Blogger

Eric and Jeff, you've introduced me to a new addiction!   :)   Thank you, and thank you DigiKey!   Excellent week!! 

I have one question, could you please direct me to some OCR resources, specifically for car plate recognition?

 

there are some great demos in OpenCV for OCR.  Check out http://opencv.org/

 

Blogger

Iron

Our pleasure, danlafleur. Glad you found the time to be of value. Best of luck on your projects!

@Eric&Jeff,   Any recomendations on a low light PTZ camera to use with OpenCV ?

 

Iron

@Eric - Did you discover any Cascades that worked better (or faster) than others ?

 

Definitely faster.  haarcascade_frontalface_alt.xml

 

Was the best tradeoff for frontal face detection and low cpu cycles.  it even ran on my Atom netbook.

 

 

Blogger

Does OpenCV integrate with LabVIEW?

 

Iron

Thanks for an interesting week of sessions Jeff, Eric, Brian and Ann.

I have a few more things to try out with a simple CV system on the bench.

I'm starting with 8x8 b/w, possibly a few gray levels to start. A hardware guy, it will be breadboarded so I can make changes at will.

Iron

Is the delay in ms??? 

 

Yes the delay is in ms

Blogger

Thanks Eric and Jeff, very informative.

Iron

Eric, do the demos allow you to capture the data?

 

If you modified the code,  the output could be redirected to a file.

OpenCV has very good support for video and image file IO.

Thank you Jeff for a week of informative presentation.

I am going to look into OpenCV to evaluate how much we can use it.

Thanks!

Iron

Thank you for all of this week's presentations!

Iron

Thanks, great lecture

Iron

great stuff! thanks for presenting to us.

 

Iron

Thank you, Great presentatiom

Iron

Hope you're feeling better by next week... Now anybody giving transportation-funding grants?? Orlando-to-Boston not TOO bad, but more than I can swing...

 

Yeah, GPS, accelerometer, etc -- but if you HAVE a camera in operation, you could do a "compare delta" to make sure everything is approximately sane.

Platinum

Want to give a big THANK YOU to Eric, Jeff and Ann for this seminar, I really enjoyed it.

Iron

Thanks Ann, Jeff, Eric, and all present.

Iron

another WOW lecture.  THANKS.

I hope I will succeed installing this OpenCV tools in one of the three OSs I've tried. :0)

Iron

THanks for the great week of presentations

So long, and thanks for all the fish.

 

Thank you Eric. This has been very helpful.
Platinum

Thanks Jeff and Eric for the great course, and Ann too!

 

Iron

Excellent work.  Thanks so much!!

 

Thkx Eric, Jeff & Ann - very good.

Iron

A lot of interesting material to study.

Iron

flared0one, might be easier to use GPS. accelerometer, etc to asertain velocity ;-) But ADAS (advanced driver assistance systems) use cameras for lots of purposes...including reading speed limit signs as you pass by them and telling you if you're going too fast ;-)

So if I was using a video camera in a car, I could actually do something VERY similar to how a laser mouse works -- [A] find the CURRENT visual features, compare to the LAST set of features, determine how things moved, add any NEW "best features to use", then loop back to [A]... if you have a calibrated imager, you could conceivably track your changing location, determine your velocity, etc -- just like a car-sized mouse... LOL.

Platinum

interesting that the system is learnt

If I remember from my Robotic Vision course, the detection algorithm was referred to as an "Expert" system, and each of the "A, B, C, D" feature types were referred to as individual "experts". And if you started with a wide range of random "features", you could figure out over time (while generating that "cascade", approximately) which features didn't matter, which ones to keep and use.

 

Ah, good clarification -- glad it IS working for you. Thought you were groaning that the update seemed to break stuff.

Platinum

 I am going to make industrial project using open CV in linux as a college study part. I am pursuing M.Tech degree. last year in that is for project.

I fiddled with the parameters, and recognition of glasses improved significantly

 

Platinum

flared0one, what I meant is that Chrome is working fine for me, even with the latest Flash plugin installed, whereas it seems that Firefox and Safari folks need to downgrade to an older Flash version in order to have audio success

Important terminology:  Face detection (is there a face present) vs. face recognition (who does that face belong  to?)

Blogger

For me happens the same, with classes the demo didn´t work. I thought it is with the pattern of detection.

Iron

Face detection/recogition is a challenging problem to solve ;-) Android 4.x includes built-in face recognition support for homescreen unlock purposes, and Google claims that it works even with glasses on, but my personal testing results have been hit-and-miss

- Which operating system(s) do you most frequently use in your products? Linux

- Which operating system do you most frequently use for your

workstations? Windows

- Besides operating systems, what kinds of off-the-shelf software

components do you use in your products?

Haar features as in Haar Transform! (Used in video Compressions) Checked paper -- yes.

http://amath.colorado.edu/courses/5720/2000Spr/Labs/Haar/haar.html

 

Iron

The characteristic patterns associated with your eyes are fairly key to the face recognition algorithm.

Platinum

face detector didnt work while I was wearing my glasses, but worked without them. There was glare on the lenses, might that be the cause?

Platinum

A lot of work on Vista VMware, Mac oS-X VirtualBox on XP, service pack problem, Linux Ubuntu lacking libraries, no success yet.

Hi Ann, Jeff, Eric and all.

Iron

Ahh -- (re latest Flash update) -- what you're seeing is how Chrome auto-updates without asking you for permission (unless you disable it)

Platinum

Oddly, Chrome (at least my copy, on Mac OS X) seems to have the latest Adobe Flash plugin version pre-installed. So it doesn't seem to specifically be the Flash plugin, per se, versus an odd browser-specific interaction

@Ann,  Embedded/Software Engineer, low light object tracking

Iron

@rzeune, try Chrome if you can -- people seem to be having good results with it.

Blogger

My Win 7 with FireFox worked perfectly yesterday.

I made the mistake of letting Adobe Flash install an update, not no audio. My IE is not configured, so I guess I'll have to wait to view the archive later....

Iron

We haven't tried the Virtualbox virtual machine manager product, but it's open source and free. Formerly a Sun product, now owned by Oracle. I believe, but am not positive, that it will import VMware virtual machines

Someone asked yesterday whether the VMware for MACs was free.

No, it is not free for Mac.  On the Mac it's calle VMware Fusion, and it costs about $50.

slide 6, could also use XOR if b/w image

Iron

So, for people scraping the chat window: if you want to stop one of the demo videos, click one of the display windows and press "space" bar.

 

Someone asked yesterday whether the VMware for MACs was free.

 

I have never yet had audio problems (on MY end) when using Chrome.

fort worth finallyy here

Comming in late to the show

Adobe Flash 11.3.300.xx with Firefox 15 works fine -- get archived version of Flash

Iron

If you're having audio issues, please note that some companies block live audio streams. If you don't hear any audio, try refreshing your browser. The show will be archived and available on this page.

Blogger

Still no adio, no joy. F5 gets me BUFFERING... but no sound. ANy help?

Iron

Products Windows based. Adding mobile Android, Apple

Develop on PC running Windows

Little open source used 

Iron

Seems like open source is a LITTLE bit more likely to have ongoing conversational access to generic "support" (in most cases its worth much more than what I'm paying for it).

Platinum

Additional audio hints from yesterday:

Mac users: yesterdays' looping issues aside, I (Mac OS 10.7 Lion) more generally was unable to hear either

yesterday or Monday's lectures via either up-to-date Safari or Firefox via the up-to-date Flash plugin. However,

Google Chrome worked (and today is once again working) fine for me.

I also observed from the comments that Windows folks running Firefox were also having problems. I'd suggest

either IE or Chrome in this case; either seemed to work for others.
