基于帧间差分的单目标/多目标的实时跟踪程序，基于MATLAB编写。希望对刚学习MATLAB的同学有所帮助-This example shows how to perform automatic detection and motion-based

　tracking of moving objects in a video　a stationary camera.

　Detection of moving objects and motion-based tracking are important

　components of many computer vision applications, including activity

　recognition, traffic monitoring, and automotive safety.　The problem of

　motion-based object tracking can be divided into two parts:



# detecting moving objects in each frame

# associating the detections corresponding to the same object over time



　The detection of moving objects uses a background subtraction algorithm

　based on Gaussian mixture models. Morphological operations are applied to

　the resulting foreground mask to eliminate noise. Finally, blob analysis

　detects groups of connected pixels, which are likely to correspond to

　moving objects.



　The association of detections to the same object is based solely on

　motion. The mo
