GraphSeg
This paper addresses the problem of segmenting an image into regions. We defi ne a predicate for measuring the evidence for a boundary between two regions using a graph-based representation of the image. We then develop an effi cient segmentation algorithm based on this predicate, and show that although this algorithm makes greedy decisions it produces segmentations that satisfy global properties. We apply the al-gorithm to image segmentation using two diff erent kinds of local neighborhoods in constructing the graph, and illustrate the results with both real and synthetic images. The algorithm runs in time nearly linear in the number of graph edges and is also fast in practice. An important characteristic of the method is its ability to preserve detail in low-variability image regions while ignoring detail in high-variability regions.

像的许多个空间中的一个。不管子空间的具体形式如何，这种方法用于图像识别的基本思想
都是一样的，首先选择一个合适的子空间，图像将被投影到这个子空间上，然后利用对图像
的这种投影间的某种度量来确定图像间的相似度，最常见的就是各种距离度量。(Like much of a space. Regardless of the specific sub-space form, this method has been applied to image recognition are the same basic idea, first of all, select an appropriate sub-space, image will be projected onto this subspace, and then use the image projection of this inter- some measure to determine similarity between images, the most common is that all kinds of distance measure.)
