region merging

As to a 3-dimension indoor scene, the technique of region merging plays an important role in keeping a reasonable partitioning, eliminating the excessive invalid portals, and consequently reducing the PVS and accelerating the rendering of large scenes.

对3D场景的入口生成而言，区域融合技术对保证划分的合理性，减少过多入口的放置，进而减小潜在可见集、提高渲染效率都起很大的作用。

secondly, after the object marker and background marker are automatically set by analyzing the structure feature of the tongue image, the proposed region merging method extracts tongue body.

其次，通过分析舌图像的结构特征自动设置目标标记和背景标记，运用提出的交互式区域合并算法提取舌象。

The technique of region merging is brought up for solving the problem of over-segmentation in 2-or 3-dimension environments.

区域融合技术是2D/3D空间里用于解决场景被过度分割问题的一种方法。

The image processing procedure such as color segmentation, run length encoding ( RLE), connected components finding, and region merging are introduced.
