这是一个用Matlab编写的程序集，可以实现一些声音和图象的处理。声音的处理有：LPC，FFT，共振峰，频谱等。图象的处理也有很多，都有源代码和参考代码。还有非常友好的界面。-This is a Matlab prepared by the procedure set, can achieve some of the voices and image processing. Voice processing : LPC, FFT, formants and spectrum. Image pro

对IQ接收器最重要的两个参数,即I和Q两路分量之间的幅度一致性和相位正交性,可采 用如下办法计算:把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一 致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比(即频域内的信号与信号镜像的幅度比) ,通过镜像抑制比和幅度一致性,可求出接收机的I和Q两路分量之间的相位正交性。-IQ receiver for the two most important parameters, namely

Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it not detected correctly it will lead wrong result in future during image analysis. During the scanning of th
