Description: We propose a novel approach for head tracking, which combines particle filters with Isomap. The particle filter works on the low-dimensional embedding of training images. It indexes into the Isomap with its state variables to find the closest template for each particle. The most weighted particle approximates the location of head. We develop a synthetic video sequence to test our technique. The results we get show that the tracker tracks the head which changes position, poses and lighting conditions. Platform: |

Description: 一套基于ZIP/霍夫曼技术的智能数据存储技术试验源代码，这里所谓的智能存储技术大约类似一个文件包,你可以添加任意格式的文件进行存储（使用AddUpdateItem函数）和从文件包中删除（使用DeleteItem函数).
你可以选择 zlib/huffman压缩模式进行压缩存储或者不使用压缩进行存储.
它采用了文件索引技术因此可以获得更好的性能,这个就是叫真空存储技术，即 VaccumStorage()函数.
而且，最重要的是，它使用序列化小节（块）技术来进行处理 CRC 和压缩大文件.
适合不需要使用数据库存储的网友，可以存储一些图片，文字甚至视频流媒体等格式。小巧方便。不使用其他ActiveX控件。
使用时先把Common\TLBs 目录中的oleguids3.tlb以及WithCompression\Test 目录下的zlib.dll 两个文件拷贝到\system32文件夹下即可打开TestWithCompression.vbg工程。-Based on a set of ZIP/Hoffman, Intelligent data storage technology test source code, here about the so-called intelligent storage technology similar to a package, you can add any file format for storage (using AddUpdateItem function) and remove the package from the file (using DeleteItem function).
You can choose zlib/huffman compression compression compression is not used for storage or storage.
It uses the document indexing technology so you can get better performance, this is called the vacuum storage technology, which VaccumStorage () function.
And, most importantly, it uses the sequence of the section (block) processing technology to compress large files and CRC.
For database storage of users do not need to store some pictures, text and even streaming video and other formats. Small and convenient. Do not use other ActiveX controls.
When used first Common \ TLBs directory oleguids3.tlb and WithCompression \ Test directory zlib.dll two files copied to the \ system32 f Platform: |

Description: Abstract—Constraining by cameras’ view-angles of the
outdoor monitoring systems, the panoramic digital images
fail to be obtained directly from photographing. A method is
proposed on the basis of the scale invariance feature
transform (i.e. SIFT) algorithm to stitch images captured by
the turning video cameras together to form panoramic
images. Based on the SIFT features and the retrofitted KD-
Tree structure, the BBF searching strategy is employed to
match feature points. Then in a post-processing pass, the
Ransac algorithm is adopted to remove the mismatching
feature points. Photos captured by a surveillance camera are
taken as the input to test the proposed method. According to
the test, the whole processing time of stitch is reduced while
the fidelity of resulting stitched panoramic images is
ensured.-Abstract—Constraining by cameras’ view-angles of the

Description: 针对传统背景建模存在的问题，文中基于低秩矩阵恢复原理，直接从视频序列中分离出前景物体和背景模型。已有低秩矩阵恢复算法的迭代计算过程中涉及大量的奇异值分解，而这些奇异值分解一般非常耗时且不够简洁，文中在非精确增广拉格朗日乘子法中引入线性时间奇异值分解算法，以得到更加有效的背景建模算法。基于
实际视频序列实验，结果表明该改进算法具有更好的建模效果和较少的运算时间。-In this paper，a novel method is present based on low-rank matrix recovery，which can directly
obtain background model as well as foreground objects from the video sequence． As the main computation
of existing algorithms of low-rank matrix recovery is the singular value decomposition，most of which are
time-consuming and not concise enough，the linear time SVD algorithm is introduced to the inexact augmented
Lagrange multiplier method，and we get a more efficient background modeling algorithm． We test
our algorithm on real video，and the experimental results show that our approach obtains good results and
less time-consuming，compared to the exact and inexact augmented Lagrange multiplier method． Platform: |
