Locate node and a reference node for random motion network model, proposed a Dynamic meshing based Monte Carlo localization algorithm. algorithm when the received reference nodes exceeds a certain threshold, the most distant node selection model selects some reference nodes involved locating and forwarding information, save energy. then based on the selection or building all received reference node sampling area, meshing, the number of grid cells used to calculate the maximum sampling frequency, the sampling area sampling and using motion model error compensation filter to improve sampling efficiency, reducing the computational overhead and to ensure a better positioning accuracy. Simulation experiments show that the algorithm in positioning accuracy,)

MATLAB视频图像考勤系统
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.)
