[matlab] facerecognizeonPCA

Description: 像的许多个空间中的一个。不管子空间的具体形式如何，这种方法用于图像识别的基本思想都是一样的，首先选择一个合适的子空间，图像将被投影到这个子空间上，然后利用对图像的这种投影间的某种度量来确定图像间的相似度，最常见的就是各种距离度量。-Like much of a space. Regardless of the specific sub-space form, this method has been applied to image recognition are the same basic idea, first of all, select an appropriate sub-space, image will be projected onto this subspace, and then use the image projection of this inter- some measure to determine similarity between images, the most common is that all kinds of distance measure.

[Industry research] High

Description: This paper presents a clustering approach which estimates the specific subspace and the intrinsic dimension of each class. Our approach adapts the Gaussian mixture model framework to high-dimensional data and estimates the parameters which best fit the data. We obtain a robust clustering method called High- Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images in a probabilistic framework. Experiments on a recently proposed database demonstrate the effectiveness of our clustering method for category localization.

Description: The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files. - space_time_coding.m (perform space time coding) - subspace_channel_estimation_STBC.m (channel estimation) - one_shot.m (show an example) To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window. Reference: [1] Ammar, N. Ding, Z.

[Communication-Mobile] Identification-Method-for-MIMO-OFDM-

Description: 对于多输入多输出系统, 传统的基于训练序列的信道辨识方法为跟踪信道的变化, 必须发送大量冗余信息, 传输效率较低而基于子空间的纯盲方法又带有不可避免的模糊性, 辨识结果精度不够。在子空间法的基础上, 利用少量训练符号估计出模糊矩阵, 以此矫正子空间法得到的结果。仿真结果显示: 在保证辨识精度的前提下, 该方法减少了训练符号等冗余, 提高了传输效率。-In o rder to t rack the channel variat ion of MIMO􀀁 OFDM sy stems, t radit io nal channel identif icat io n methods based on training sequence had to send larg e amount of redundant informat ion, w hich result s in low er eff iciency o f t ransmissio n. Meanw hile, the blind method based o n subspace may have inevitable ambiguity and low er precision of identif icat io n. In this paper, an est imat io n method fo r the ambiguity mat rix is proposed, which utilizes less tr aining symbo ls to rect ify the result s f rom subspace method. T he simulation result s show that this pro posed algo rithm can reduce the amount of t raining symbols and incr ease the ef ficiency of t ransmission.
