现有大屏拼接技术性能参数对比，这是我上个月的调研内容，数据可信，对于要了解大屏拼接技术的人一定有帮助(Existing large-screen display technical performance parameters comparison, this is my last month s survey content, data credibility, for large-screen technology to understand who must have help)

基于轨迹划分的异常轨迹检测方法。首先采用两种分段粒度将每条轨迹分为若干子轨迹线段，然后，在基于距离的异常检测方法的基础上，引入调整系数的概念，采用密度与距离相结合的方法进行异常轨迹检测。 (Abnormal trajectory detection method based on trajectory partition.Firstly each trajectories should be divided into several substrajectories using two granularities. Then the notion of adjustment coefficient is introduced on the basis of distance based anomaly detection method, and the abnormal trajectories are detected combining density and distance. )

支持向量机在小波包去噪方法中的应用，小波包分解和svm相结合(Support vector machines in wavelet packet denoising of wavelet packet decomposition and combination svm)

自己编写的C++小程序，十字算法，用到KD树，能够有效进行点云去噪，压缩数据(I have written a small program C++, cross algorithm used in KD tree, the point cloud can be effectively de-noising, compression of data)

本解码器类支持普通jpeg文件格式，这也是目前大多数jpeg文件所采用的格式，此格式主要特点是数据精度为8位，采用Huffman编码的普通DCT帧（不支持扩展串行和递进模式及数学编码）。本解码器类的 IDCT算法采用三种模式，分别是浮点解码、定点整数解码和定点整数MMX优化解码，您可根据具体情况选择。(The decoder class support common JPEG file format, which is currently the most JPEG files in the format and the main characteristics of this format is data for 8-bit precision, using Huffman coding DCT common frame (does not support extended serial and progressive model and arithmetic coding). The decoder of the IDCT algorithm uses three modes, respectively, floating-point decoding, fixed-point integer decoding and fixed-point integer MMX optimization, you can choose according to the specific circumstances.)

水印要求完全不被修改，完全脆弱水印一般是从空域LSB算法演变而来。(Watermark demands nothing to modify, the fragile watermark is completely general LSB algorithm has evolved the airspace。)

检具设计工具 运行于ug3d设计软件环境。支持2.0以上。有些版菜单本会出现乱码(The tool design tool runs in the ug3d design software environment. Support more than 2. Some of the versions of the menu would have been messed up)

快速ＤＣＴ变换的代码.利用c++实现DCT变换.(Fast DCT transform code. Use c++ to achieve DCT transform.)
