一种比较好用的音频水印嵌入程序，基于MATLAB实现的。(A relatively easy to use audio watermark embedding process, based on the MATLAB implementation.)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

the file consists of image segmentation using otsu threshold and finally counting by using the creating the boundary between of them

说明：  MATLAB视频图像考勤系统 该课题为基于MATLAB的摄像头的图像考勤系统。调用笔记本自带摄像头，从左侧进入为正1，右侧出去为负1，每统计到一个人数记为正负1.点击开始和点击结束为一个周期。带GUI界面。另外可定制二次开发基于图像的人数考勤系统。(Matlab video image attendance system The subject is the image attendance system of camera based on MATLAB. Call the camera equipped with the notebook, enter from the left as positive 1, exit from the right as negative 1, and record the number of each person counted as plus or minus 1. Click start and click end as a cycle. With GUI interface. In addition, it can customize the secondary development of image-based attendance system.)
