可以从一幅含有头和肩部的图像中检测出人脸，并用矩形框框起来，将矩形框中的人脸裁剪出来并另存为80*80的图片(Can be detected an image containing a head and shoulders of a person' s face, and the frame up with a rectangle, the human face of the rectangular box to cut out and save it as 80* 80 pictures)

frequency domain filtering codes for matlab - creating the test signal -creating frequency domain filter - applieying the filter and computes a filtered signal - plotting both in time domain and frequency domain

this metal detector full project (pulse induction)

1、理解小电流接地系统的概念； 2、理解中性点不接地和经消弧线圈接地系统单相故障的特点； 3、学会用MATLAB/Simulink进行小电流接地系统的建模与仿真。 (1, understand the concept of small current grounding system 2, understand the neutral point ungrounded and arc suppression coil grounding system single-phase fault characteristics 3, learn to use MATLAB/Simulink for small current grounding system modeling and simulation.)

说明：  关于有限长冲击响应数字滤波器的matlab设计(On the finite impulse response digital filter design matlab)

model haye pofaki baraye dor zadane pudn

this is a code to calculate the moment invariant of images. the values which come out are capable of removing rotational, scaling, transnational variation in image given as input.classification can be done with the help of it.

说明：  使用MATLAB平台运行的一个完整的DBSCAN聚类算法(A Complete DBSCAN Clustering Algorithm Running on MATLAB Platform)

This code is hopfield neural network. However, not my work
