Detailed Network Measurements Using Sparse Graph Counters: The Theory
Measuring the network traffic network counter memory storage counters
2015/8/21
Measuring network flow sizes is important for tasks like accounting/billing, network forensics and security. Per-flow accounting is considered hard because it requires that many counters b...
The fastest mixing Markov process on a graph and a connection to a maximum variance unfolding problem
Markov process fast mixing second smallest eigenvalue semidefinite programming dimensionality reduction
2015/8/10
We consider a Markov process on a connected graph, with edges labeled with transition rates between the adjacent vertices. The distribution of the Markov process converges to the uniform distribution ...
Indoor Navigation System for the Visually Impaired with User-centric Graph Representation and Vision Detection Assistance
Indoor Navigation System Visually Impaired User-centric Graph Representation Vision Detection Assistance
2014/12/8
Independent navigation through unfamiliar indoor spaces is beset with barriers for the visually impaired. Hence, this issue impairs their independence, self-respect and self-reliance. In this thesis I...
Adaptive Image Deblurring via Tanner Graph Representation and Belief Propagation
Adaptive Representation Belief Propagation
2013/7/24
Image deblurring aims to counteract the effect of point spread function (PSF) inimperfect image formation system. Conventional solutions include frequency-domainapproaches (e.g. Wiener filtering...
Generation and Evaluation of Business Continuity Processes using Algebraic Graph Transformation and the mCRL2Process Algebra
business continuity business process algebraic graph transformation process algebra generation evaluation enterprise modeling
2014/3/11
Critical business processes can fail. Therefore, continuity processes are needed as back-up solutions. Today, those continuity processes are set up and maintained manually. They are mostly based on be...
Frucht Graph is not Hyperenergetic
energy of a graph hyperenergetic frucht graph automorphism
2013/1/29
If are the eigen values of a p-vertex graph , the energy of is . If , then is said to be hyperenergetic. We show that the Frucht graph, the graph used in the proof of well known Frucht’s theorem, is n...
基于Skip Graph的P2P覆盖网信任证链发现
Skip图 信任证 信任证链
2009/8/10
提出一种基于Skip图 P2P覆盖网模型的分布式信任证存储和发现机制。为保证索引和发现效率，采用 语言作为信任证描述语言，其语义属性作为Skip图中的索引关键字，构造了基于关键字前缀相似和支持范围查询的P2P覆盖网。通过试验评测和分析，该机制具有较高的查询效率和负载均衡机制。
Offline Signature Verification Using Graph Matching
Offline Signature Verification Graph Matching Thinning Normalization
2009/7/28
In this paper, we present a simple and effective signature verification method that depends only on the raw binary pixel intensities and avoids using complex sets of features. The method looks at the ...
MULTI-POLARITY TEXT SEGMENTATION USING GRAPH THEORY
Text processing Image segmentation Graph theory
2013/7/17
Text segmentation, or named text binarization, is usually an essential step for text information extraction from images and videos. However, most existing text segmentation methods have difficulties i...

2013/7/17
Places in movies and sitcoms could indicate higher-level semantic cues about the story scenarios and actor relations. This paper presents a novel unsupervised framework for efficient place retrieval i...
A Force-directed Graph Drawing based on the Hierarchical Individual Timestep Method
visualization graph drawing Internet Map
2010/2/2
In this paper, we propose a fast and efficient method for
drawing very large-scale graph data. The conventional force-directed
method proposed by Fruchterman and Rheingold (FR method) is
well-known...
