IMAQ for LabView photo image
Hello
I use the XY graph to display GPS data, XY graph also displays a map that is be pre-processed using vision functions to display a correct part of the image data, climb the ladder etc.
Everything works fine, but the average standard conversion
long (25 ms). He becomes hostile user, when all scales / relocation of the XY graph introduces a delay.
IMAQ vision preprocessing takes about 25ms too, as well as other calculations, the user's response is about 60ms, and it's just so - so to use.
I hope to cut treatment time here, because he just flattening a table.
I started to do my own IMAQImage2LVPic function, but little success, because I do not understand the Image of the LVPicture format, I get distorted images, violations of memory, and it becomes frustrating.
The structure of the memory of the LVPicture would be nice to know. Help, please.
Rather than drawing in the PlotImage of the XY graph, have you tried to make the transparent XY graph (which includes both the background of the chart and also control encompassing) and placing it in front of a screen of Vision? Then, you will not need conversion. I have not tried, so I don't know if there may be problems with the speed of drawing, flicker or aliasing, but it might be interesting to try.

Train of SVM IMAQ for no Image data
Hello
I am fairly new to machine algorithms for learning about Labview so please be patient if my question seems stupid. I was wondering if there is a workaround to use the screw of Machine Vision SVM (e.g. IMAQ SVM Train) for not the image data. I know Machine learning package and I will surely give it a try with those but MV screws are really well organized and allow to record the training in a very elegant manner.
Indications, suggestions or, well, even a "no, can't it' is really appreciated!
Moreover, any luck of having the learning algorithm Machine present natively in LV?
Thank you
FRAX
-According to my knowledge IMAQ screws are specifically for the Images.
-Your best chance is using Machine learning package that you have already found.

HP Photo &; Imaging program
Is it possible to steal the HP Photo & Imaging program disc for printer Officejet PSC 2100 originally installed on WIndows XP and install just part of the drivers and utilities for Windows 7? Don't need of printer drivers, I have a new printer. But, although the Photo program and imaging - easy to resize photos. Original installation disk does not support Windows 7. Workarounds for HP will allow you to print and scan in Windows 7, but I do not see the PHoto and imaging program. THX.
Hey Kathy. There is unfortunately no way to choose only the Photo & Imaging program on the full package of pilot. Resizing of the pictures is the only reason for that software? There are many other programs freeware out there that would allow you to do this.
Good luck!

Excerpt from IMAQ (-1074396077), crop the Image
Hello
I have a 12-bit (Vosskuhler) CCD camera. I use the vi IMAQ, to take the image of the camera CCD the IMAQ Snap.vi. Communication to the camera works very well...
I want to crop the image 'full', take a rectangular area in the interest of this image. For this, I use the Extract.vi IMAQ.
Problem: when I try to crop directly the image that is from the camera, the Extract.vi IMAQ generates an error (-1074396077). BUT when I first save the image on a local disk, reload again and try to cut back then, then it works properly! What can be the problem?
I have attached the vi that does not work...
Thanks a lot for your help
PS: I mean I have a solution with the save, close, and charging, but I don't like this!
Cheers, Matthias
Hello MJ77
You can see what image type a vi came out of the snap function and also the ability to load from a file attached.
I get the same error as you if image types are not the same.
