小波变换在信号处理、图像处理、模式识别中的研究…
小波变换在信号处理、图像处理、模式识别、计算机视觉等
方面广泛应用。本文提出了一种基于Haar小波的时问序列相似
模式匹配模型．它首先对时间序列数据进行Haar小波变换．以
降低数据的维度。首先将所要查询的时间序列进行降维，也就是
对时间序列数据进行小波变换，对序列进行标准化131，得到降维
之后的小波序列．这样可以得到系数子集的良好近似采用尺度
序列表示原始序列．并将其看成多维空间中的一个点，通过计算
两序列差的平方和的平方根作为这两个时间序列的距离函效
(即欧氏距离)。用小波变换保持了局部性质。而欧氏距离就是要
判断相似性的距离函数．所以当在作完变换之后。通过低频分量
来压缩数据，成功的计算出实际距离的下界。如果计算的结果小
于一个由用户所定义的门槛值．则认为这两个时问序列是相似
的。

The Joint Video Team (JVT) of ISO/IEC MPEG and ITU
The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. This document describes the transform and
quantization processes defined, or implied, by the standard.-The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard forthe coding (compression) of natural video images. The new standard [1] will be known as H.264 andalso MPEG-4 Part 10,

RESTful...
RESTful Java with JAX - RS Edition December 2009 Retail Ebook-ATTiCA
-Learn how to design and develop distributed web services in Java using
RESTful architectural principals and the JAX-RS specification in Java
EE 6. With this hands-on reference, you ll focus on implementation
rather than theory, and discover why the RESTful method is far better
than technologies like CORBA and SOAP. It s easy to get started with
services based on the REST architecture..
