Dear all,
I have developed various microscopy image segmentation algorithms using MATLAB (mostly based on built-in functions from the Image Processing Toolbox).
The segmentation works very well for individual, standalone frames but I would like to use it to track movements of objects over time. More specifically, I would like to know when new objects appear, when 2 existing objects merge, etc. The objects move slowly and can easily be follow by eye when playing the movie.
I thought it would be a straightforward endeavour as I already have a very reliable segmentation algorithm. But I was unable to find an elegant way of doing it. I started playing with a crude approach that keeps track of the positions of the various objects overtime and detects events of note (merging, splitting, etc...). But I feel like I am reinventing the wheel and was wondering if there is more reliable and proven approach to such a problem.
Thanks in advance for any recommendation!
Nicolas

This kind of capability is in the Computer Vision System Toolbox. Have you checked out any of those demos and see if they can be applied to your videos?
