摘要
提出了一种新的基于光照不变性模型的阴影消除方法。首先对二维光照不变性图像恢复阴影,再利用基于互信息的图像融合去除运动目标的投影,最后通过图像镜像消除边界条件的制约,改善阴影去除效果。实验结果表明,该方法能够有效地消除运动目标的阴影。
A new Shadow removal method based on illumination invariant was introduced,for moving object detection.First,shadow for 2D image were restorated based on illumination invariant.Second,method combined with mutual information and brightness was presented.Finally,we mirrored the original image set so that no original shadow edge consolidated with a boundary of the image.The experimental results show that the method can solve the problems of lighting and shadows,suppress shadows effectively.
