Research on three image difference algorithm
Baofeng Zhang, Jie Zhou, Junchao Zhu · 2010
The method of frame difference is a commonly used way for moving targets detection because it is simple to compute and easy to realize, but it has defects. The moving object captured will present a “double image” phenomenon, so it is difficult to extract goal accurately. This article proposes three image difference algorithm to capture moving target, which, with statistics and curve fitting method, confirmed its rationality and validity. It also simultaneously avoided “double image” phenomenon. The experiments show that it is practical and effective.
