背景差法中的阴影消除方法

Shadow suppression method for background subtraction

依据视频图像序列中运动目标分割的一种重要方法背景差法的,提出一种新的计算颜色模型,使用该模型能够有效地计算色度差,解决了背景中光照亮度渐变和背景物体移动等问题,从而解决了运动物体的阴影消除问题。利用该方案实现了人体检测系统,并对该检测系统在室内和室外进行了多组实验。实验结果验证了所提出的方案——新的阴影消除方法的有效性。

Background subtraction is a typical technique used for real-time segmentation of moving objects in video sequences. To cope with background change problems such as gradual illumination changes and moved background objects, to cope with shadow problem, a new computational color model is proposed. Chromaticity distortion is measured in an effective way. Experiments have been performed on a surveillance system in indoor environments as well as outdoor environments. The experimental results demonstrate the effectiveness of the proposed approach - a new shadow suppression method.
