A Random Walks View of Spectral Segmentation , by Marina Meila

چکیده
Thus, NCut is small when a partitioning of the graph produces two partitions that are both high in volume, containing many vertices with a high sum of similarities to other vertices, but where the sum of the similarities between vertices in different partitions is small. The NCut problem is to find a partition of the graph which minimizes the NCut criterion. Minimizing the NCut for a graph, however, has been shown to be NP -hard by Shi and Malik.

Learning Segmentation by Random Walks
The context here is image segmentation because it was in this domain that spectral clustering was introduced by Shi and Malik in 2000. Meila and Shi provide a random-walk interpretation of the spectral clustering algorithm, and then use a transition probability matrix to create a model which learns to segment images based on pixel intensity (which they call “edge strength”) and “co-circularity”...
متن کاملA Random Walks View of Spectral Segmentation
We present a new view of clustering and segmentation by pairwise similarities. We interpret the similarities as edge ows in a Markov random walk and study the eigenvalues and eigenvectors of the walk's transition matrix. This view shows that spectral methods for clustering and segmentation have a probabilistic foundation. We prove that the Normalized Cut method arises naturally from our framewo...
متن کاملUnsupervised Spectral Learning
In spectral clustering and spectral image segmentation, the data is partioned starting from a given matrix of pairwise similarities S. the matrix S is constructed by hand, or learned on a separate training set. In this paper we show how to achieve spectral clustering in unsupervised mode. Our algorithm starts with a set of observed pairwise features, which are possible components of an unknown,...
متن کاملSpectral Clustering: a Tutorial for the 2010’s
Spectral clustering is a family of methods to find K clusters using the eigenvectors of a matrix. Typically, this matrix is derived from a set of pairwise similarities Sij between the points to be clustered. This task is called similarity based clustering, graph clustering, or clustering of diadic data. One remarkable advantage of spectral clustering is its ability to cluster “points” which are...
متن کاملCochlea segmentation using iterated random walks with shape prior
Cochlear implants can restore hearing to deaf or partially deaf patients. In order to plan the intervention, a model from high resolution μCT images is to be built from accurate cochlea segmentations and then, adapted to a patient-specific model. Thus, a precise segmentation is required to build such a model. We propose a new framework for segmentation of μCT cochlear images using random walks ...
