HTML5拖放选择图片、删除选择功能，上边有几个按钮，分别是选择全部，全部不选，删除，也可以鼠标点选任意一个图片，点击Delete后可动态删除这张图片，当然只是在列表中删除，并不是真正把图片从硬盘上删除。HTML5效果，所以请在支持HTML5的浏览器中查看效果。

这是一篇关于相机标定的文章。该方法的特点是使用LCD屏幕而不使用棋盘格标定板。(This is an article about camera calibration. The characteristic of this method is to use LCD screen instead of checkerboard calibration board.)

H无穷控制针对马尔科夫调变系统的非脆弱控制研究。(This paper gives attention to the issue of nonfragile state estimation for a class of Markov jump systems with repeated scalar nonlinearities and redundant channels.)

SOM-SVM模型是利用SOM的聚类特点，将含有相同特征的输入样本聚集在一起，并把离聚类中心较远的输入样本舍去。经过20%的样本压缩后，将含有代表性的小样本再送入SVM进行训练。本文的样本集通过实验平台采集，验证了基于支持向量机的频谱感知方法在实际数据测试条件下也能取得很好的感知性能。仿真结果表明，SOM-SVM模型在低信噪比下，频谱检测率接近100%，检测错误率也得到了很好的改善。(The SOM-SVM model is based on clustering characteristics of SOM, the input sample will contain the same features together, and the input samples from far down the clustering center. After 20% samples were compressed, the representative samples were sent to SVM for training. In this paper, the sample set is collected through the experimental platform, and the spectrum sensing method based on support vector machine is proved to be able to achieve good perception performance under the actual data testing conditions. The simulation results show that the detection rate of SOM-SVM model is close to 100% at low SNR, and the detection error rate is also improved.)
