| 摘 要： | 提出了一种复杂背景下的手部图像分割方法。首先,在YUV颜色空间建立了YUV肤色模型,再利用摄像机对背景持续观测一段时间,建立背景的统计模型,然后将两种模型结合,对当前手图像进行分割,最后对分割后的图像进行形态学滤波、空洞填充与中值滤波等处理得到最终分割的手势。实验结果表明,此种方法算法简单,分割效果好,非常适用于复杂背景的手势分割与识别。

| Abstract: | A method of hand image segmentation from complex backgrounds is presented.First,a skin model based on YUV color space is established,then by sampling consistently with a USB camera,a background statistical model is constructed.After that the two models are combined to segment the hand image,the final segmented hand is obtained by using the morphology filter, empty holes filling algorithm and median filter.The experimental results demonstrate that the proposed method is very suitable for the hand gesture segmentation and recognition from complex backgrounds,since its algorithm is easy and effective. |
