基于MATLAB的齿轮箱振动故障诊断的程序(Gearbox vibration fault diagnosis based on MATLAB program)

"1D FDTD solution for open boundary in a unitless domain with a Courant factor > 1 (Unstable solutions leading to blow-up)"

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.
