symmetrical difference scheme 对称差分格式
symmetrical difference method 对称差分解法
maximum symmetrical difference 最大对称差
The symmetrical difference can quickly detect the object shape, gain more reliable background model and is more adaptable to the changeable environment.
即利用对称差分能快速检测出中间帧运动目标的形状轮廓的优点,使用间隔多帧的对称差分进行背景模型的动态更新,得到可靠的背景模型,并通过调整间隔的帧数来实现环境变化的可适应性。
