摘要: 提出一种可靠的色彩建模方法,建立基于亮度变化的色彩统计特征数学模型,其特征包含随亮度变化的色度、饱和度的均值以及标准偏差,应用B样条对模型进行曲线拟合,实现彩色图像分割。实验结果表明,该算法的分割效果较好,鲁棒性强,能够适应不同光照条件下彩色图像的分割。

Abstract: A reliable color modeling approach is proposed, through which a color statistical characteristic mathematical model based on brightness variations is set up. The features of this model contains the chroma changing with brightness, the mean of saturation, and standard deviation. The curve fitting is conducted to this model by using B-spline curve, which implements the color image segmentation. Experimental results show this algorithm has better effect of segmentation and strong rubustness, it can be applied to the color image segmentation in different lighting conditions.

Key words: color image segmentation, B-spline curve, brightness variation
