      Hello, 
      I'm trying to implement an object tracking in LabVIEW. I've written a VI (attached) to detect and locate the centroid of elliptical shapes (because my circular subject can possibly be rotated and appear as an ellipse). However, the detection is not successful on every frame.
      For this reason, I would like to use the object detection method I've written as a ROI reference for an object tracker, whereby the object detector runs every 10-20 frames or so to make sure the tracker has not accumulated too much error. Any advice on how I can do this? Thanks! 
      Additionally, any criticism or advice on my object detection method would be appreciated.

      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 without any problem. I have attached the VI and info regarding the video, could you guys please let me know why I am having problem when I am trying to display the video in the reverse order.

      New Toolkit : OpenCV wrapper for Raspberry Pi (LinuxRT) for LabVIEW
      Great ! learning platform student and maker for learning machine vision application with LabVIEW.
      It's working with LabVIEW Home 2014 edition and  required LINX 3.0 toolkit.
      You can run NI-VISION toolkit with Raspberry Pi board too.

      Hello everyone,
      We have started with the development of our own embedded MIPI camera module for the Raspberry Pi with an industrial image sensor. Currently we are in the specification phase and we are interested in your preferences so we will develop a product that does fit your requirements. If you have some time, please consider filling in this 4-question questionnaire.
