用共轭梯度算法——PRP算法求解无约束最优化问题(Conjugate gradient algorithm- PRP algorithm for solving unconstrained optimization problems)

说明：  该源代码是Leo Grady，基于随机游走算法来实现的图片切割(The source code is Leo Grady, based on random walk algorithm to realize the image cut)

这是一个改进的自适应canny算法，该方法采用改进的开关型中值滤波器对图像做去噪工作，再把整幅图像分割为若干子图像，最后在充分考虑全局以及各子图像的边缘梯度信息后，自适应地生成动态阈值。(The new Canny adaptive method divides image into sub-images,then determinates the thresholds automatically according to the whole image edge information and the sub-images edge information.)

瑞利信道下，2发2收，最大似然译码，空时编码，MATLAB仿真实现(Rayleigh channel, 2 admission, maximum likelihood decoding, space-time coding, MATLAB simulation)

计算自然样条曲线的MATLAB程序 输入的量X和Y分别是由节点（x_i,y_i）（i=0,1,2,...,n）的横坐标和纵坐标组成的向量。(A Matlab program for calculate natural spline)

包括面积、周长、矩形度、伸长度，基于小波变换的数字水印算法matlab代码，小波包分析提取振动信号中的特征频率。( Including the area, perimeter, rectangular, elongation, Based on wavelet transform digital watermarking algorithm matlab code, Wavelet packet analysis to extract vibration signal characteristic frequency.)

信号检测理论上机实验MATLAB源码,关于一阶预测器的设计(Signal detection theory, experiment MATLAB source code, on the first-order predictor design)

LSB算法，将二值（0，1）图像嵌入到指定图像（256*256）中，从第一位到第八位。(LSB algorithm, the two values (0,1) image is embedded to the specified image (256* 256), from first to eighth.)

说明：  additive white gaussian noise in matlab

说明：  Shrink the image by a factor of two using the bilinear interpolation and zoom this image to the original size again. Does this image differ from the original one?
