代码说明:

小波的matlab实现,Harr小波分解,Harr小波重构,如果需要压缩80%,则对分解后的系数及 按照绝对值大小进行排序,保留其中占20%绝对值相对较大的系数,然后按照信号重构方法对保留的系数进行重构,这样就可完成压缩。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.

    高斯过程是一种非参数化的学习方法,它可以很自然的用于regression,也可以用于classification。本程序用高斯过程实现分类!(Gaussian process is a non- parametric method of learning, it is very natural for regression. can also be used for classification. The procedures used to achieve classification Gaussian process!)
