[vehicle detection] multi vehicle detection on road based on background difference method with matlab code

1 brief introduction

Moving target detection is one of the main research contents in the field of digital image processing, pattern recognition and computer vision , It is also an important field of computer vision research . The algorithm of video target detection based on background difference method is studied . With Matlab As the main research tool , Detect the moving target in the video . The principle and algorithm of background difference method are studied , It is discussed and analyzed in detail . The median filter background model is used to extract the background , The shadow of the target is detected and suppressed . Experimental results show that , Using this algorithm to detect moving targets has good accuracy and stability .
