Conventional block-based image classiication algorithms, such as CART and VQ based clas-siication, ignore the statistical dependency among image blocks. Consequently, these algorithms often suuer from over-localization. In order to beneet from the inter-block dependency, an image classiication algorithm based on a hidden Markov model (HMM) is developed. An HMM for image classiication, a two dim...

On my block, it's like the world don't exist. We stay confined to this small little section with dividends," proclaims hip-hop artist Scarface in his composition "On My Block." From the perspective of the artist, then, his neighborhood, figured adequately as a block, takes on the qualities of a corporeal, three-dimensional square: one both confining and small. The impression of the artist, voic...

Three-dimensional geological modeling is widely used in the field of research. A successful three-dimensional model a anatomy and integration study area. Large-scale limited by software performance technical difficulties. There are disadvantages such as unequal splicing elements, morphological distortion attribute incompatibility. Based on discrete storage method DepthInsight software, this pap...

The signature block is a common structured component found in e-mail messages. Accurate identification and analysis of signature blocks are important in many multimedia messaging and information retrieval applications such as email text-to-speech rendering. It is also a very challenging task, because signature blocks often appear in complex twodimensional layouts which are guided only by loose ...

A new type of two-dimensional automaton has been defined to recognize a class of twodimensional shifts of finite type having the property that every admissible block found within the related local picture language can be extended to a point of the subshift. Here it is shown that this automaton accurately represents the image of the represented twodimensional shift of finite type under a block c...

High dimensional unconstrained quadratic programs (UQPs) involving massive datasets are now common in application areas such as web, social networks, etc. Unless computational resources that match up to these datasets are available, solving such problems using classical UQP methods is very difficult. This paper discusses alternatives. We first define high dimensional compliant (HDC) methods for...

We introduce a computable estimator of block entanglement entropy for many-body spin systems admitting total singlet ground states. Building on a simple geometrical interpretation of entanglement entropy of the so-called valence bond states, this estimator is defined as the average number of common singlets to two subsystems of spins. We show that our estimator possesses the characteristic scal...

A bstract Recently, with the help of Parisi-Sourlas supersymmetry an intriguing relation was found expressing four-point scalar conformal block a ( d ? 2)-dimensional CFT in terms five-term linear combination blocks -dimensional CFT, constant coefficients. We extend this dimensional reduction to all higher-point arbitrary topology restricted exchanges. show that coefficients appearing finite te...
