Research on Moving Object Detection Algorithm Based on Improved Three Frame Difference Method and Optical Flow

For optical flow algorithm complexity,computationally intensive, poor real-time drawbacks ,thispaper proposes a moving detection algorithm that combinewith optical flow method and three frame difference methodwhich be used OTSU to process. Choose the typical Harriscorner of extracting area to calculate, it can effectively reducethe complexity of the algorithm. Since moving target areadetection was not complete, the three-frame difference imagewhich be processed by OTSU binary image was introduced asa supplement of simplify the optical flow method. Through theexperiment, this method make the optical flow method satisfiedthe real-time request . Detect more complete area of themoving object.
