摘要

提出了一种新的实时阴影检测与消除方法。与现有方法相比，色调和饱和度直接在yuv色彩空间中近似。我们展示了阴影对yuv值的线性影响，并在快速决策方案中利用了这种行为。该方法鲁棒性好，无需进行色彩空间变换即可实现实时视频处理。

Fast and robust shadow detection in videoconference applications

A new approach for real-time shadow detection and elimination is presented. In contrast to existing methods, hue and saturation is approximated in the YUV-colour space straight away. We show the linear influence of shadow to the YUV-values and exploit this behaviour in a fast decision scheme. The proposed method is robust and capable for real-time video processing without any need of colour space transformations.
