Hi Everyone, I am trying to play the video in reverse decrementing the frame number in IMAQ Read Frame function. Its working but the result is very choppy as every frame takes significant time to load, but when I just increment the frame number and play the video forward, its executing wi...

Hello, I need one help regarding changing the image image type How can I convert grey scale image to false color image? Here, I have attached two images. 1. greyscale image 2. is just an example that I want to convert. (False Color). Any help would be appreciate....

Understandably NI's own line of analog video frame grabbers have been obsolete for some time (since 2010 I believe). I have an industrial application where I am bound to using legacy analog VGA cameras. Upgrading the cameras is not an option I would like to use LabVIEW for testing purposes...

In the attached image I have four Code 128 and two Code 39. I have problem detecting them without down sampling the image first. Since I want to grade the bar codes I don't want to down sample since the code quality is reduced then. I noticed this from that sometimes some of the bar codes are found...

I have a relatively large application which does heavy IMAQ image processing. Many IMAQ buffers are created and destroyed dynamically at runtime based on need (i.e. different system components will create their own temporary images for processing steps and destroy them when their work is finished)....

Hello to all. First of all thanks a lot for reading this post and being able to help. I have noticed the next problem: My application has a camera, this camera takes images (snap mode) and application process them (detect some edges in the image). It works fine. But when I make t...

Hello to all. I have an image and a ROI. I would like to get the minimun distance between the first edge and the last edge in horizontal position. See image attached. If every edges found are in color yellow I would like to get the distance between edges in red (minimun distance from...

Hello, I have begun a VI to manipulate jpg : the VI takes 2 jpg, convert them to BW, scales and translates them and finally superimpose recompile them as different color channel (Red and Green) of a new image. This does work well until the recombination step : I cannot get any output from...

I would like to try and upgrade my current CCD (pretty close to 640x480) to a higher res model (1080p). Here are my two requirements: It has to work LabVIEW/Vision software (could interface through GIG-E/IP or whatever) It has to fit inside of a tube about this size: (marker for scale) http://i....

In my job I develop in-house machine vision and image processing solutions for my company. In industrial machine vision and inspection, there are several main players (Cognex, Keyence, Matrox, Halcon, etc.) LabVIEW and IMAQ are not totally out of the picture but are far from common for manufact...

Hello, I am having a bit of an issue applying a threshold to an image and getting reliable results. I am thinking using edge detection prior to doing any other image processing could make this work... but I am at a loss for how to implement it. If you look at the image below you... -
Hi all, I am using a Atmel Aviiva camera in my application. I need to change some camera parameters permanently. So , as I learnt through web, I can do it by editing the associated *.icd file. But the aviiva files look different. They contain the camera parameters for all interface types. (i.e., P... -
Hello everyone, i am new to this forum, i am working on a pattern matching project and i require some assistance . I have made a VI of my own after going through the pattern matching example included in the LabVIEW exmaples. unfortunately i am getting stuck in the pattern matching of the...

Mostly for fun, I have concocted a way of acquiring video using Labview for linux, to mend for the unavailability of IMAQdx. The idea is to grab via v4l2, actually through the handler libv4l2, and to display simply via the picture control. I have tested this for the moment only with webcams at 640x...

Hi, I am wondering if anyone did or found a performance test of IMAQ functions. What I am interesting in is what is the performance of IMAQ functions compared to functions written in .net or C++ (OpenCV)? Can we improve or deteriorate the performance of IMAQ based applications? regards, Marcin

I want to make an exe application from a .vi to install on another non-labview-installed machine (I want to use the runtime engine). The only problem I can foresee is that I built the software on a version of Labview that has all the add-ons, and I don't know which ones I have used. I want to know...
