虚拟信号发生器是一个GUI产生（1）周期函数（包括正弦，三角，锯齿，和方波）不同振幅，频率和阶段 （2）不同振幅平方脉冲序列，频率，分期及职责循环 （3）双参数指数函数 （4）高斯曲线之间的范围不同，标准偏差和手段，以及（5）不同幅度的高斯噪声。你也可以添加一个偏移或高斯噪声的前四个以上任何职能。图形用户界面还能使用户可以添加指定的信号（或者乘以它的）一个先前定义的信号。 -Virtual Signal Generator is a GUI that produces (1) periodi

Choice of Wavelets for Image Compression In wavelet-based image coding the choice of wavelets is crucial and determines the coding performance. Current techniques use computationally intensive search procedures to find the optimal basis (type,

Adaptive Wavelet Image Compression This report describes the Adaptive Wavelet Image Compression (AWIC) algorithm in detail. This is a fast, efficient image compression technique which often produces better image quality than JPEG, the current i

本程序实现任意偶数大小图像第二代双正交97提升小波变换 注1： 采用标准正交方法，对行列采用不同矩阵（和matlab里不同）-Even the size of the program to achieve any image to enhance the second-generation bi-orthogonal wavelet transform 97 Note 1: The standard orthogonal method, the ranks of the different
