General Description
The blob tracking system includes 5 modules as depicted on diagram.
This pipeline is called “Blob Tracking Auto” module and implemented as individual module in
BlobTrackingAuto.cpp and BlobTrackingAuto.h files.
“FG/BG Detection” module performs foreground/background segmentation for each pixel.
“Blob Entering Detection” module uses the result (FG/BG mask) of “FG/BG Detection” module
to detect new blob object entered to a scene on each frame.
“Blob Tracking” module initialized by “Blob Entering Detection” results and tracks each new
entered blob.
“Trajectory Generation” module performs a saving function. It collects all blobs positions and
save each whole blob trajectory to hard disk when it finished (for example tracking is lost).
