中文说明： 毕业设计有用，包括最后计算压缩图像的峰值信噪比和压缩效果的源码,利用matlab写成的窄带噪声发生，针对EMD方法的不足,能量谱分析计算,毕设内容，高光谱图像基本处理。
English Description：
Graduation design useful, including the final calculation of peak signal to noise ratio of the compressed image and compression of the source, written using MATLAB narrowband noise generation, shortage of EMD method, analysis and calculation of energy spectra, based content, hyper-spectral image basic processing.
