edgedetect

Given a point, it finds whether the point is inside or outside of the polygon, given polygon vertices.

小波分析数据包，用于信号的时频分析。通常用于信号的分析(Wavelet packet analysis, used in the signal time-frequency analysis)

QR二维条码模式识别，可有效识别出条码的模式信息(QR barcode pattern recognition, which can effectively identify the bar code mode information )

子空间分解matlab程序。采用PCA主成元分析方法。(Subspace Decomposition matlab procedures. Using PCA Principal Component Analysis.)

说明：  matlab下实现对高斯噪声下的小目标的滑窗检测。数据为1000个点，滑窗窗口大小为30，每次滑动一个点的数据。采用的是窗内30个数据先各自平方，然后求和，再除以窗口大小。实验表明能有效检测雷达目标信号。(matlab under Gaussian noise to achieve a small target detection sliding window. Data for 1000 point sliding window window size is 30, each time moving a point of data. Using the data before the window each 30 square feet, and then summed, divided by the window size. Experiments show that the radar target signal can be detected.)
