blob_tracking

event-based blob tracking. Tracking a blob of moving events, which can be anything, people/cars (see the picture below).

Features

• Blob initialization, blob tracking, and blob kill
• Up to about 2Mb events/s processed on an Intel i7 CPU, single thread

Usage

dependencies

gflags is needed for parameter settings. Download and compile: here.
OpenCV is optional only for visulization. Install it before or comment the codes for visualization.
Tested on Ubuntu 18.04, OpenCV 3.2.

Clone, compile and run.

# clone 
git clone https://github.com/LarryDong/blob_tracking.git

# modifty the `path` in main.cpp

# compile 
mkdir build && cd build
cmake .. && make

# run:
./blob_tracking <--parameters>      # check the sorce file to see parameters.

Limitations & Issues

• The blob size is fixed to be a circle with constant radius, but can be easily modofied.
• Cannot merge/split two blobs when two blobs come together/apart, easily to be implemented.
• No denoise process, which may cause computation burden on noisy environment.
