这是一个关于MATLAB音频信号的分析与合成程序方面的ppt(This is a ppt about the analysis and synthesis of speech signals using MATLAB)

This interactive game allows you to manipulate and view the rubik s cube in 3D with the click of your mouse. If you get stuck, just click to watch the cube solve itself. Or, just "rearrange the stickers" and start over.(This interactive game allows you to manipulate and view the rubik s cube in 3D with the click of your mouse.

the above codes are very useful for image segmentation,edge detection

本程序描述了kalman滤波算法，利用初学者加深对kalman滤波算法的理解。(This procedure describes the kalman filter algorithm, the use of beginners to deepen the understanding of the kalman filter algorithm.)

In this paper, we show how support vector machine (SVM) can be employed as a powerful tool for $k$-nearest neighbor (kNN) classifier. A novel multi-class dimensionality reduction approach, Discriminant Analysis via Support Vectors (SVDA), is introduced by using the SVM. The kernel mapping idea is used to derive the non-linear version, Kernel Discriminant via Support Vectors (SVKD). In SVDA, only support vectors are involved to obtain the transformation matrix. Thus, the computational complexity can be greatly reduced for kernel based feature extraction. Experiments carried out on several standard databases show a clear improvement on LDA-based recognition
