Shape-Detection

用于提取心音包络的程序，编译运行较好，有界面显示。(Used to extract the heart sound envelope program, compile and run better, there are screen displays.)

说明：  基于人眼视觉模型的双正交小波变换算法，通过实验验证,该算法在对嵌入水印后的图像进行有损压缩、剪切、污染、添加各种噪声等处理后,提取出的水印仍表现出了较好的鲁棒性。(Human visual model based on biorthogonal wavelet transform algorithm, experiments show that the algorithm of the watermarked image lossy compression, shear, pollution, after adding all kinds of noise, the performance of the extracted watermark is still a good robustness.)

有关于数字信号处理的水印技术，成功运行，除水印效果很明显(Digital signal processing on the watermarking technology, successful operation, in addition to obvious watermark)

電磁波,天線設計與分析工具箱,包含大量範例(Electromagnetic waves, antenna design and analysis toolbox, including a large number of examples)

智能天线中多单元圆形天线阵的波达方向估计(Smart antennas in multi-element circular antenna array of the Direction of Arrival Estimation)

很好的Adaboost自学实例，简单易懂(A simple but robust Adaboost exmaple, which is easy enough by self-learning)

Median Filtering using MATLAB for filtering image

512点FFT程序，分10级蝶形运算完成。(512-point FFT program, sub-10 butterfly to complete.)
