Labview or Labwindows CVI for Machine Vision

[akang]

I am working on a Machine Vision research project which involves entensive image capturing and processing. I am using Labview now. My question is what the difference is between Labview and Labwindows in terms of performance in processing speed.  Even in Labview, I call some C dll I developed myself. In this case, if I switch to Labwindows  CVI , can I expect some performance improvement? If, yes, approximately how much by experience ? 

Thanks

Hello,

I can't directly answer your question because I've never used LabWindows CVI...

What I can tell you is that you can expect approximately 10% speed improvement on image processing by building an executable.
Of course the improvement will depend on  how you  developped your application. It is quite easy to make beginner's mistake that result in a slow application ; if I say this it because when I started image processing I went through many beginners mistake .

Could you describe more or less your process ? Image type and size, framegrabber, camera, acquisition rate and the data flow you would like to process ?

    I noticed that this is a duplicate posting with the thread below.  I can understand the reasoning but if it is possible, try to avoid duplicates.  Give a posting time to be resolved before posting to another thread.  Otherwise, you could narrow you questions down for that particular thread (Vision specifics in the Machine Vision thread and LabVIEW dll calls in the LabVIEW thread) The threads are meant to get you the most specific help to your issue. We appreciate it, thanks.
