We present the ”Cartoon Animation Filter”, a simple filter that takes an arbitrary input motion signal and modulates it in such a way that the output motion is more ”alive” or ”animated”. The filter...
The advent of new standards in wireless communication like the Long Term Evolution (LTE) has resulted in a need for newer and better design of receivers for wireless communication systems, the first s...
针对骨干网上异常检测的特殊要求,提出了一种基于Filter-ary-Sketch数据结构的异常检测方法。该方法通过Filter-ary-Sketch实时记录网络流量信息,然后每隔一定周期进行基于多维熵值的异常检测。如果出现异常则根据Filter-ary-Sketch记录的流量信息进行异常点定位,最后利用Bloom Filter中记录的源IP信息进行恶意流量阻断。该方法能够检测多种类型的网络攻击,且...
在三态内容寻址存储器(Ternary Content Addressable Memory, TCAM)表项宽度和存储容量约束下,该文提出一种基于匹配表项压缩的BF-TCAM算法,采用Bloom-Filter(BF)对匹配关键字进行单字节编码压缩关键字长度,解决了匹配吞吐率低和存储空间不足问题。针对BF在表项压缩过程带来的冲突率上升问题,引入向量存储空间策略,利用向量存储空间实现多个哈希函数映射,...
拥有一个有效的一致性维护机制是保证P2P系统正常运行的关键之一。非结构化P2P系统中的消息传播主要通过邻居的转发,会产生大量冗余消息;并且,系统中节点的物理位置和逻辑位置存在着不匹配,会增加消息传播的时间开销。为减少一致性维护代价,该文提出基于物理位置与Bloom-filter的副本一致性维护机制。该机制利用复杂网络中社团划分思想,将网络中的节点按物理位置划分成多个簇,簇中节点物理位置相近,让更新...
The main problem of particle filter (PF) in nonlinearstate estimation is the particle degeneracy. Resampling operationsolves degeneracy to some extent, but it results in the problem ofsample impoveris...
因RTD-GPS定位精度不能满足农田导航作业的需要,研究了一种提高农用车辆自动导航定位精度的方法。建立天线补偿模型,对GPS天线晃动引起的误差进行了补偿;建立基于Kalman滤波模型,融合多传感器信息;使用自主开发的基于VRS的GPS接收机,作为RTD-GPS。将RTD-GPS、电子罗盘以及速度传感器获得信息进行Kalman滤波,其结果和高精度GPS数据进行了比较。实验证明,直线跟踪中,平均偏差由...
This letter considers carrier recovery for offset quadrature phase shift keying (OQPSK) and minimum shift keying-type (MSK-type) modulations based on phase-lock loop (PLL). The concern of the letter i...
This paper proposes a fast and effective image interpolation algorithm using median filter. The interpolation algorithm is composed of two steps. First, a non-linear iterative procedure is utilized ...
In this paper, a novel multiple objects detection and tracking approach based on support vector machine and particle filter is proposed to track players in broadcast sports video. Compared with previo...
Particle filter is a powerful visual tracking tool based on sequential Monte Carlo framework, and it needs large numbers of samples to properly approximate the posterior density of the state evolution...
AVS is Chinese new audio and video coding standard, in which a loop filter has been applied to remove blocking artifacts. A platform-based architecture for the loop filter of AVS standard is proposed ...
