basic_models

python-wapiti is a python wrapper for wapiti (http://wapiti.limsi.fr), a very nice sequence labeling tool with support for maxent models, maximum entropy Markov models and linear-chain CRF.

本程序详细描述了电磁波在水下传输的衰减模型，随着频率的增加，信号衰减愈加明显。(This procedure describes in detail the electromagnetic wave transmission attenuation model of underwater, with the increase of frequency, signal attenuation are becoming ever more obvious.)

Function that calculate the PSNR and WSNR of two imagines

说明：  各种波束形成方法的集合，非常好用，当然，非原创。(A collection of various beamforming methods, very easy to use and, of course, non-original.)
