A Gunshot Recognition Method Based on Multi-Scale Spectrum Shift Module

نویسندگان

چکیده

In view of the issues such as larger network model and lower recognition accuracy current gunshot networks, a neural based on multi-scale spectrum shift module is proposed in this paper to fully mine relevant information among spectrums. This employs architecture densely connected convolutional uses branch realize interaction information. replaces under-sampling operation spectrums, realizes globalized feature extraction spectrum, avoids loss during process, further improves quality map. Experiments were conducted NIJ Grant 2016-DN-BX-0183 dataset YouTube gunshots that have been open public, both whose classification reached 83.2% 95.1%, respectively, with size being controlled at around 16 MB. The experimental results indicate that, compared other existing methods for network, can time-frequency better effectively, has higher recognition.

ON THE MAXIMAL SPECTRUM OF A MODULE

Let $R$ be a commutative ring with identity. The purpose of this paper is to introduce and study two classes of modules over $R$, called $mbox{Max}$-injective and $mbox{Max}$-strongly top modules and explore some of their basic properties. Our concern is to extend some properties of $X$-injective and strongly top modules to these classes of modules and obtain some related results.

PRIMARY ZARISKI TOPOLOGY ON THE PRIMARY SPECTRUM OF A MODULE

‎‎Let $R$ be a commutative ring with identity and let $M$ be an $R$-module‎. ‎We define the primary spectrum of $M$‎, ‎denoted by $mathcal{PS}(M)$‎, ‎to be the set of all primary submodules $Q$ of $M$ such that $(operatorname{rad}Q:M)=sqrt{(Q:M)}$‎. ‎In this paper‎, ‎we topologize $mathcal{PS}(M)$ with a topology having the Zariski topology on the prime spectrum $operatorname{Spec}(M)$ as a sub...

Numerical solution of nonlinear SPDEs using a multi-scale method

‎In this paper we establish a new numerical method for solving a class of stochastic partial differential equations (SPDEs) based on B-splines wavelets‎. ‎The method combines implicit collocation with the multi-scale method‎. Using the multi-scale method‎, ‎SPDEs can be solved on a given subdomain with more accuracy and lower computational cost than the rest of the domain‎. ‎The stability and c...

Real-Time Object Recognition Based on Cortical Multi-scale Keypoints

In recent years, a large number of impressive object categorisation algorithms have surfaced, both computational and biologically motivated. While results on standardised benchmarks are impressive, very few of the best-performing algorithms took run-time performance into account, rendering most of them useless for real-time active vision scenarios such as cognitive robots. In this paper, we com...

Action Recognition Based on Multi-scale Oriented Neighborhood Features

The spatio-temporal (ST) position information between local features plays an important role in action recognition task. To use the information, neighborhood-based features are built for describing local ST information around ST interest points. However, traditional methods of constructing neighborhood, such as sub-ST volumetric method and nearest-neighbor-based neighborhood method, ignore the ...
