- 将要传输的信号通过子带结构分成四路信号,分别通过预先调制滤波器组,在接收端收到信号,经过自适应滤波,然后形成一束波(The signal to be transmitted is divided into four signals by subband structure, and the signals are received at the receiving end through the pre modulation filter bank, and then a wave is for

- 根据现有的程序,对两幅图像分别进行二维小波变换,分别对变换后得到的水平,垂直以及对角细节子带的小波系数进行直方图统计,然后用广义高斯函数去近似三个直方图,分别得到尺度参数和形状参数,求出对应图像的KL距离。(According to the existing programs, the two images respectively, two-dimensional wavelet transform respectively to levels after transformation, ve

- 本程序是基于单幅图像的超分辨率算法,通过对输入的高分辨率图像进行下采样得 % 到原始低分辨率图像,对输入的低分辨率图像插值后,利用DWT将低分辨率图像分 % 解为不同的4个子带;同时直接对对分辨率图像进行SWT处理。由SWT得到的高频子 % 带来修正DWT得到的高频子带。最后,通过逆离散小波变换(IDWT)组合修正的高 % 频子带和低分辨率图像,得到输出的超分辨率图像。通过计算PSNR和SSIM评价结果。(This prog
