对Lena图像128*128，进行QF=50和QF=40的压缩，然后解压缩，并分别计算压缩图像的PSNR，给出图像压缩后的图像(Lena image of 128* 128,QF=50 and 40 compression, then uncompress, and calculate the PSNR compressed image, after image compression)

This is a complete program for speaker recognition based MATLAB. It uses VQ(vector quantization) method to detect different speakers.

This is a program to calculate the Photonic Bands of two dimension Photonic Crystal with circular inclusions. It calculates both TE and TM modes (E and H polarization).(This is a program to calculate the Photonic Bands of two dimension Photonic Crystal with ci rcular inclusions. It calculates both TE and TM modes (E and H polarization).)

实现利用高斯分布聚类，即完成em算法，直接在matlab上运行，可以作图直观显示（二维数据）(Achieve Gaussian distribution clustering, complete em algorithm, running directly on matlab, you can visualize mapping (two-dimensional data))

lazy snapping的算法，是image matting的一种方法(lazy snapping algorithm is a method of image matting)
