Adaptive Background Image Calculation for Video Sequences Based on Optical Flow
Hui Zhu, Xiao Peng Ji · Advanced materials research · 2014
A new method is proposed to calculate the background in video sequences. The optical flow is estimated to determine the local regions occupied by moving objects. The background image is calculated by an efficient averaging process excluding the moving object regions, which overcomes the foreground-occluding problem in direct averaging method for background estimation. The experiments for traffic video processing prove the method’s effectiveness and robustness.
