摘要
针对彩色图像中照明引起的过分割问题,根据人类视觉中的颜色恒常特性,提出了利用相邻区域的颜色分布的连续性作为基准进行区域合并的方法.连续性采用区域内像素的马氏距离定义的椭球的主轴方向夹角来表示.实验表明该方法对过分割有很好的抑制作用.
In order to solve the ex-segmentation problem experienced in the process of segmentation, a region consolidation method based on the succession of color distribution was proposed. The succession is expressed by a general ellipsoid's main axis angle determined by Mahalanobis distance of pixel distribution in the close area. Experimental results show that this method can restrain ex-segmentation very well.
