SAR图像压缩感知图像处理，用于压缩感知处理后的SAR图像进行图像重建与恢复(SAR image compression sensing image processing, image sensing processing for compressing SAR image after reconstruction and restoration)

何恺明等人研究出的基于暗通道的经典图像去雾算法，不仅可以还原图像的颜色和能见度，同时也能利用雾的浓度来估计物体的距离。(The classic fog removal algorithm based on dark channel, which was developed by He Kaiming and others, not only can restore the color and visibility of images, but also can estimate the distance of objects by using the concentration of fog.)

Matlab binary digits for handwritten character recognition

基于切片法计算船舶的耐波性，matlaB编程计算数据处理(Slicing method based on the ship' s seakeeping, matlaB programming data processing computing)

对matlab初学者很有帮助，尤其是simulink的爱好者。(helpful to beginners Matlab, Simulink is particularly fond.)

The architecture of this set of codes and the interaction among them is shown in Figure 1. The main testing code main code.m calls the code riemann grad unit opt.m that performs Riemannian optimization under unitary matrix constraint. Steepest Descent/Ascent (SD/SA) algorithm (see Table 3.2 in [1]), Conjugate Gradient (CG-PR, CG-FR) algo- rithms (both Fletcher-Reeves and Polak-Ribi`ere formulas, see Table 3.3 in [1]), are im- plemented. This code further calls the codes implementing line search methods: Armijo method geod search armijo.m, as well as the polynomial and DFT-based approximation

数字吉他效果器仿真之TREMOLO（颤音效果）(TREMOLO simulates a guitar tremolo stomp box)

应用背景在这个例子中你实现了LPC分析合成（LPC编码）的语音信号。这个过程包括两个步骤：分析和合成。在分析部分中，提取信号的反射系数，并用它来计算残差信号。在合成部分中，利用残差信号和反射系数对信号进行重构。剩余的信号和反射系数需要更少的比特数比原来的语音信号。关键技术在这个模拟中，语音信号被分成3200个样本的帧的帧，与1600个样本的重叠。每个框架窗口使用汉明窗。第十二阶自相关系数被发现，然后使用杜斌-莱文森算法的自相关系数计算的反射系数。原始语音信号通过一个分析滤波器，这是一个所有的零滤波器的反射系数为以上。滤波器的输出是剩余信号。这个残留的信号是通过一个合成过滤器，这是逆的分析过滤器。合成滤波器的输出是原始信号。
