Spectral clustering methods are useful for partitioning data which are anisotropic or otherwise generated from non-Gaussian dis- tributions, such as images. As the amount and resolution of images continues to grow, distributed analysis frameworks are increas- ingly needed in order to break the data...

在 Image Processing 领域里已经有许多自动或半自动的算法来解决这个问题,并且有不少方法和 Clustering 有密切联系。比如我们在谈Vector Quantization的时候就曾经用 K-means 来把颜色相似的像素聚类到一起,不过那还不是真正的 Segmentation ,因为如果仅仅是考虑颜色相似的话,图片上位置离得很远的像素也有可能被聚到同一...
事实上,Jianbo Shi的这篇 PAMI paper:Normalized Cuts and Image Segmentation正是把 NormalizedCut 用在图像分割上了。 搬出RatioCut 和 NormalizedCut 是因为它们和这里的 Spectral Clustering 实际上有非常紧密的联系。看看 RatioCut ,式子虽然简单,但是要最小化它却是一个 NP 难问题,不方便求解,为了找到解决办法,...
A novel approach is presented for synthetic aperture radar (SAR) image segmentation. By incorporating the advantages of maximally stable extremal regions (MSER) algorithm and spectral clustering (SC) method, the proposed approach provides effective and robust segmentation. First, the input image is tra...

Spectral clustering is one of the most important image processing tools, especially for image segmentation. This specializes at taking local information such as edge weights and globalizing them. Due to its unsupervised nature, it is widely applicable. However, traditional spectral clustering is O(n3...
We present a novel approach for solving the text segmentation problem in natural scene images. The proposed algorithm uses the normalized graph cut(Ncut) as the measure for spectral clustering, and the weighted matrices used in evaluating the graph cuts are based on the gray levels of an image...
