Sarah Mclachlan... :thumbup: Great voice...

And, happily, not all her songs are sad. Think of the hugely popular remix of "Silence" made by Delirium (although the lyrics to that one are somewhat sad) or of "Possesion" (my personal favorite) which is not really sad and which I find an incredible song.

Here you can find many Sarah's songs here, below is a direct link to Adia, but there are many others listed on the side too.

Last summer I wrote something here (you can search to find it if you want, no big deal, many times I always regret what I wrote and maybe today too, very soon ).

I always wanted to write things, but I know I am not really that good at it. I regret that I didn’t learn more flowery language when I was little, so that now I can stream out these magnificent flashy words without thinking. Now that whenever I need to write things, I need to use the scan mode, one word by one word. I have a feeling that most part of my brain is only one bit (which makes up only two value, very simple, I guess you all know how to calculate ). A small part of it maybe 12 bit, a very small part maybe 16 bit, a very very small part maybe xxxxxxxxx bits?? I don’t know

Anyway this summer I always wanted to leave some words for the memory of next years, but I didn’t do it until now when the snow is coming. Yes, we had a light snow since yesterday already, a bit earlier than usual. Snow like feather falling down from no-where up there, so light, so beautiful, so cold, so lonely, so quiet, hitting on the window and melting away (ok, I try to be expressive ). Sitting in the warm caf

Here's a blog by Hall Martin of NI discussing the future of GUI's and the trend towards 3D.

Hmm, interesting to see there are software to let you browsing through your file folder in 3D. While you are waiting for NI 3D block diagram, you can also check out our 3D webcam for fun if you want.

Ok, maybe too off topic, but this 3D webcam does have some link to LabVIEW through the use of IVision LabVIEW toolkit or other labview toolkit that is directshow compatible.

Don't chat flat, show the world more aspect and depth with HYTEK 3D iVCam.

Hello Ni Hao!

I don't know what you exactly want to identiy or just tracking the human face. If you just want to track human face with color, you can try out using the color spectrum if you want to use IMAQ vision, maybe you can first learn the object color (like human face color), that way you will get color spectrum for the human face, then you can search the whole image (maybe with the same ROI you used to learn the color object) to find the closest ROI where the match score is high. But this is not the best way. Normally people use Camshift method, like what OpenCV uses. I used to have a LabVIEW toolkit called ObjTracker that implements this Camshift method to track human face based on color, but we don't sell/support this toolkit anymore. Attached is a document about camshift method for your reference, hope it does not make more confusion.

thanks,

Irene

My name is ttkx, from china.

how do you think i can identify the human face using IMAQ and if there is any labview example code or any other details which can help me please send me the necessarry information as early as possible.

I already got image from USB Camera with LabVIEW, I try some methods with Vision toolkit , but the result is unsatisfactory.

Hello r8000,

Below is how I do it, hope you find it useful. It also called false color image, used to represent like temperature value etc. Is this what you are looking for?

First get the LUT(lookup) table for all three colors (RGB:red, green, blue), this can be done by modifying the NI LabVIEW shipping example "Color Table Generator.vi" in the "Create IntGraph Color Table.vi" example. If you don't know where to find this example, go to LabVIEW menu Help->Find Examples->click on search->type in "Intensity", it should list the vi "Create IntGraph Color Table.vi", the "Color Table Generator.vi" is a subvi in it. Then apply the lookup table conversion vi with either IMAQ vision or IVision toolkit to your original gray image, you also need to create three gray destination images (same size as your original gray image) to hold for the LUT converted gray images for all three RGB channels, let's call it rImage, gImage and bImage. Now you can compose a color image with these three rImage,gImage and bImage gray images, both IMAQ vision and IVision toolkit have this compose color image vi.

thanks,

Irene

I want to display and store an image of grayscale type as a rgb type but i want to get

different colors for each rang of grayscale. I thought to operate this with threshold, but then lubview convert my image to 8-bit type , so I thought to change the image by insert relevant luts row , how can I get luts like rainbow, temperature and the like

psdeo-color can't help me because i need my image as rgb.

thanks.

:!: Disclaimer: I mean no malice in my comments below - please take them at purley face value.

Don't worry, I understand it's only discussion about the subject. And when I mean "you" in my above post, I don't really mean you, just general "you".

Ok, I agree that if possible, go to attend some courses certainly is useful than not to, but not everybody thinks it's necessary for their current work. And if there are some books cover the similar topics as CLA instead of attending courses and getting certification, that may be useful for people who don't really care the title of CLA, but still want to learn. But that may not be good for NI...I don't know.

I hope this is my last post for this thread, too much time, don't want to be addictive

Out now!

Well, what's so big deal getting certification? Anyone (even high school graduates) can get it in a couple of months. Just because you think you are "good" at LabVIEW does not turn you into a microwave expert, fiber optics expert, rocket scientist... Don't make it sounds so big as if only the people who owns the certification has EXPERIENCES? Would be top programmer? You just make LabVIEW sounds so SHALLOW. Getting certification is fine, but you don't necessary have the right to judge other people's work.

Very droll Irene (or, at least, I think you're being droll - you forgot to add a smiley to the end of that sentance )

Ok,

Is anyone else having trouble receiving messages from Info-Labview, or does anyone know of anything wrong with it? I haven't received a message in about 5 days, and subscribe requests are bounced back as 'no such domain.' Thanks.

Yes, I am worried too. But last digest I received was May 1 digest version.

I thought this had been fixed before LabVIEW 8, but up until now I'd never had a need to check:

......

Hmm... too bad that CLA courses do not teach how to solve problem.

Easy to think it's a bug, but it may not be, you are missing subvis (I will explain below).

[Advertisement ON]

Well, I have figured this out and have been using this plug in technique for quite a FEW years. This plug in technique especially has been intensively used in IVision callback vis and our standalone end application (only LabVIEW runtime engine needed) that uses IVison and data acquisition dynamic called engines etc. Our applications (this and this) have been distributed in different countries with different local languages without problem.

[Advertisement Off]

Make the EXE only for the top level vi, you don't need to include dynamic called vis. Then make a llb for all dynamic called vis, then save the dynamic called vis out of the llb in a folder. And of course your top level vi should point to the right path where these dynamic called vis are. I guess (I am not NI, so guessing) you got error message because your dynamic called vis are broken because couldn't find some subvis. LabVIEW runtime engine does not know where to search for subvis, unlike development environment.

NI Certification is an important milestone on the path to LabVIEW enlightenment (which is more of a journey than a destination). If someone thinks she's good at LabVIEW and she hasn't taken any courses or obtained NI certification, then chances are she's not as good as she think's she is and she probably doesn't have the experience that our organization is looking for. (I'm also responsible for hiring LabVIEW developers.) A certification requirement for hiring certainly makes for a good filtering criterion (and you can't have too many). At our organization, we require that every LabVIEW developer be on a professional path to become a Certified LabVIEW Architect.

I am not sure why people use "She", since most majority LabVIEW people are "He". If you happen to mean me, then I can tell you that I have never thought I am a great LabVIEW programmer, I know there are people who can make a lot nicer user interface and some other people have a lot more experiences on engineering which is more important as a LabVIEW programmer. But that doesn't matter to me, there are more things to make you good other than a certification.

By the way the person Ben mentioned with initial RK, that definitely not me, but if that is the person I would guess, I do think he is a great person. So hiring people maybe should consider more than just LabVIEW certification. Some people are just so unpleasant to work with that would depress the team work.

I also don't think certification is the most important thing, some people work better without stress. If a boss takes the certification so seriously, it properbly not a good and wise place to work for anyway. (by the way, I am not saying this because I failed many certifications in my life, as a matter fact, opposite side...)

In worst case if you still can't get it work directly using LabVIEW installer, maybe you can try to use a third party install builder. I usually only build *.EXE file in LabViEW, then use third party installer to include all necessary files. I also include a *.bat file which that I can use to launch automatically after the installer exit. (there is a setting in the third party installer will allow you do this). Inside this *.bat file, I add the LabVIEW runtime engine installation program and others like usb drivers, so that everything will be installed at the end. This has always worked for me. The third party install builder that I use is called "Install Creator". They even have a freeware which you can still use, just have an advertisement at the end.

Irene

Well,

NI has extended the USB driver to several extra languages including (out of memory):

Dutch

Chinese

Polish

and hopefully for rgouvasiur Portuguese [?] as well

But you have to download the dll from the NI forums board!

Ton

That is not my point... I meant that NI should be able to provide a version that do not have to deal with language problem. Many directshow toolkit and applications don't have trouble to ask customers providing their OS languages. I know NI engineers are diligent to add more languages, but they don't have to.

funny... I happened to check out NI discussion forum, this is what NI fellow suggest/support user:

"

1. Roll back to SP1

2. Go to an Italian, Japanese, French, or English OS. These languages have work with the NI-IMAQ for USB driver.

"

Hmm... if I don't know any languages stated above, I have to use one of these OS? It's easier to just blame MS for languages localization, but it's hard to say if it's totally MS's fault. If NI (or whoever works on this) is smart enough (sorry), they should have made it languages independant...other than blaming MS. Seems NI is pretty busy enhancing this USB camera features.

Sometimes I felt pretty foolish to stay loyal to any company even I like one of their tool if they don't give it's users any room to be creative/interactive and kill everything extra other than just wanting users to follow the company entirely.

Whatever.

By the way, this is what I replied at NI forum:

Easier if we had a body suit, "body glove". But with data gloves we would already see the gloved hands in the 3D field.

But some people may like to see themself in action, not a simulated hand.

Data gloves idea sounds pretty good. We can also walk into the 3D scene to do the wiring, can we? So programming LabVIEW needs a Camera and a green background behind you

Hmm... it seems that no matter what topic we started originally, people have always a way to end it up with beers, delicious food. Don't get me wrong, I enjoyed reading this, and I'm not totally against alcohol for the sake of healthy heart. (suggestion to Admin: can we put a flag to warn people about Alcohol or Non-Alcohol topic? LabVIEW programmers could be under 17, couldn't they?). Great food is always good, no matter how great things we do (like LabVIEW programming ), we can't get rid of eating, can we?

Happy Easter!

Figuring now where to go

Which 3D are we talking about here?

3D picture controls or graphs allow to display a and rotate objects as 3D objects projections but it is not 3D stereo vision where you need some way to send two different images one to each eye.

In the former case we see a flat image and the brain figures depth from perspectives and relative sizes. You see the same thing even with poor eyesight on one eye.

In the latter case the brain receives two images and then it can figure depth with its hardwired ability to integrate these two images into a 3D representation.

When I talked about 3D, actually I had the latter case in my mind because I actually had some heat more than a year ago about anaglyph image and even wanted to get something out of it... but I cooled down But I may still do it, it's not something huge, but it's fun. We drove one hour to see "The Polar Express" before Christmas in 2004 in the late night, it felt like a dream.

But I think if LabVIEW would go for 3D, the first case maybe more suitable?

Actually The Polar Express is using the polarized method, so different glasses than red/cyan glasses.

Irene

Oh, really this was talked in year 2000? Well, I have never seen and read this before, I only start paying attention to LabVIEW forums 2-3 years ago (coincidently I also posted something regarding audio probing before in info-labview one or two years ago). So that can only mean that great mind think alike

Hi, I don't feel confident to add this officially to LabVIEW wish list yet, so I'd post it here first. Would it be possible to make a special LabVIEW version that can be seen as 3D (like using red/cyan glasses or special LED monitor) so that all controls would be real 3D and we can see multi-layer of case structure in 3D etc? (mouse click would lead to one special case scene), so that we have more room in block diagram (no one need to complain anymore that they don't get big enough screen) since we add one more dimension? That would add more fun to already fun LabVIEW programming cause it's coding in dream , not in reality.

Oh my God, I see 3D... I mean anaglyph image.

Your so funny.

Ok, I know I've spent too much time on the forum, now I really need to get back to do some real meaning making thing. But, just one more question, so you can control your eye balls separately?

Have a nice day.

Irene

Thank you everyone who replied to this thread. It is very helpful for me to read how other people think about being freelance or work by themself. Whatever situation you described, they helped to firm the thoughts. Maybe everything has two sides, it's up to each person to find the balance.

Very good reading of each replies. They all tell a very interesting story, opinions and experiences.

Thank you.

Irene

Very nice song and lyrics. Impressive, Enrique!

Irene

Hello, I think some people here maybe a freelance or one person company or independant consultant. I would like to hear how do you feel about working alone by yourself? What keep you doing this way and how long do you hold on it and if giving up, why? What is good and what is bad about being a freelance? The good part for me is the freedom to schedule the time and work/create things that I like. Bad part is you are alone, no inspiration by others and missing the fun of talking with co-workers etc.

What is your experiences?

Irene
