matlab: ComputerVision, cell count and multiObject tracking demo.

Here is a short video to demo some of the stuff you can do with the Computer Vision toolbox in matlab. The code i used is based on different examples provided by the matlab website  (cell count and object tracking)
I still find the mathematics behind the scenes very difficult to understand but fortunately the matlab provides a certain degree of abstraction and at a some point i found myself tweaking specific functions based on some cryptic morphological parameters of the data and managed to port the code provided by matlab to work on the video i recorded previously with my usb microscope.
watch the video and have a look at the results:
