I'm looking to track the motion of a particle using imaq

[Simy]

I am looking to motion track a spherical particle through a series of images and was wondering if anyone would know how to do this. The particle will probably change size depending on the image.

Hello Simy:
Well size definitely will be the deciding factor first here (I'm doing laser scanning microscopy) because your choice of vision components will depend on that, thing like resolution is ultimately determined by the smallest "particle" you need to see. That also translates to choosing a camera which can do the job.There could be several combinations of IMAQ Vision VIs/Image processing algorithms to make this work maybe some even have to be customized with codes written Visual C++ or MathLab -- for instance using BLOB (binary large objects) with combinations of Thresholding and even calculations of center of gravity and assigning scores to each to chracterize them. If the particles are on top of each other you have to do a "segmentation" with combinati
on of erosion,dilate etc. to highlight boarders etc. It's gonna be a lot in fact something that cannot be gotten from LabVIEW itself but from other source like books on signal/image processing. Most of it will be a lot of readings about the subject matter of course your ideas could tested initially by creatin scripts from another software package called IMAQ Vision Builder. Good luck!
