Anomalous percolating properties of growing networks
We describe the anomalous phase transition of the emergence of the giant connected component in scale-free networks growing under mechanism of preferential linking.

Text Detection in Natural Image By Connected Component Labeling
The process of detect the text from the natural image is complex and difficult process because the variance by the devises that take the images and different the texts that found in images in the orientation, size and style.

To achieve a good trade-off between the data-embedding payload and the data-embedding distortion, mainstream reversible data hiding (RDH) algorithms perform data embedding on a well-built prediction error histogram.

Connected Component Labeling Using Quadtrees [PDF]
Abstract : An algorithm is presented for labeling the connected components of an image represented by a quadtree. The algorithm proceeds by exploring all possible adjacencies for each node once and only once. Once this is done, any equivalences generated by the adjacency labeling phase are propagated.

On the existence of a connected component of a graph
We study the reverse mathematics and computability of countable graph theory, obtaining the following results. The principle that every countable graph has a connected component is equivalent to $\mathsf{ACA}_0$ over $\mathsf{RCA}_0$.

Efficient Parallel Connected Component Labeling With a Coarse-to-Fine Strategy
This paper proposes a new parallel approach to solve connected components on a 2-D binary image. The following strategies are employed to accelerate neighborhood exploration after dividing an input image into independent blocks: 1) in the local labeling ...

Ancient Chinese Character Image Segmentation Based on Interval-Valued Hesitant Fuzzy Set
To address the low segmentation accuracy caused by the rich glyph styles of ancient Chinese characters and the complex layout of ancient Chinese books, which affects the retrieval and recognition results, an algorithm for the layout image analysis of ...

Maintenance of Strongly Connected Component in Shared-memory Graph
In this paper, we present an on-line fully dynamic algorithm for maintaining strongly connected component of a directed graph in a shared memory architecture. The edges and vertices are added or deleted concurrently by fixed number of threads.

A remark on the connectedness of spheres in Cayley graphs [PDF]
The aim of this small note is to prove an elementary yet useful properties of finitely presented groups. Let G be a finitely generated group with one end. Fix a (finite) generating set and let $B_n$ be the ball of radius $n$ around $e$.
