基于MATLAB的图像处理及跟踪算法

摘 要

摘 要

视频图像处理技术广泛用于工业、安全、医疗、管理等领域。运动目标的检测和跟踪是图像处理技术在视频序列图像处理方面的一个重要应用，在航天、交通、机器人视觉、视频监控、公共场所客流数据监测等场合发挥着重要作用。

本文介绍了一种基于MATLAB的简易的从视频播放的帧图像中找出目标图像，并进行视频跟踪的实现方法。通过对图像进行阈值处理（图像分割），再对分割后的图像求取形心，以对目标图像进行定位，并最后找到各幅帧图像的目标位置的方法，从而实现对100帧视频图像的实时跟踪。

ABSTRACT

ABSTRACT

Video image processing technology is widely used in industrial, security, health care, management and other fields. Motion target detection and tracking is image processing technology in video sequence is an important application in image processing, in the aerospace, transportation, robot vision, video surveillance, public traffic data monitoring plays an important role.

This paper introduces a simple MATLAB to find the target image from the video image frame based, and realization method of video tracking.Through the threshold of image processing (image segmentation), then the after image segmentation to obtain the centroid, to locate the target image, and finally found the method of each frame image of the target position, so as to realize the real-time tracking of the 100 frame of video images.

Key words: target detection; threshold; video object tracking; centroid estimation
