Abstract

The discipline of computer vision is becoming more popular as a research subject. In a surveillance-based computer vision application, item identification and tracking are the core procedures. They consist of segmenting and tracking an object of interest from a sequence of video frames, and they are both performed using computer vision algorithms. In situations when the camera is fixed and the backdrop remains constant, it is possible to detect items in the background using more straightforward methods. Aerial surveillance, on the other hand, is characterized by the fact that the target, as well as the background and video camera, are all constantly moving. It is feasible to recognize targets in the video data captured by an unmanned aerial vehicle (UAV) using the mean shift tracking technique in combination with a deep convolutional neural network (DCNN). It is critical that the target detection algorithm maintains its accuracy even in the presence of changing lighting conditions, dynamic clutter, and changes in the scene environment. Even though there are several approaches for identifying moving objects in the video, background reduction is the one that is most often used. An adaptive background model is used to create a mean shift tracking technique, which is shown and implemented in this work. In this situation, the background model is provided and updated frame-by-frame, and therefore, the problem of occlusion is fully eliminated from the equation. The target tracking algorithm is fed the same video stream that was used for the target identification algorithm to work with. In MATLAB, the works are simulated, and their performance is evaluated using image-based and video-based metrics to establish how well they operate in the real world.

摘要

计算机视觉学科作为一个研究课题越来越受欢迎。在基于监控的计算机视觉应用中,项目识别和跟踪是核心程序。它们包括从一系列视频帧中分割和跟踪感兴趣的对象,这两个步骤都使用计算机视觉算法完成。在相机固定且背景不变的情况下,可以使用更简单的方法检测背景中的项目。然而,航空监视的特点是目标以及背景和摄像机都在不断移动。使用均值漂移跟踪技术结合深度卷积神经网络(DCNN)可以识别无人机(UAV)拍摄的视频数据中的目标。目标检测算法即使在光照条件变化、动态杂波和场景环境变化的情况下也能保持准确性,这一点至关重要。尽管有几种方法可以识别视频中的移动物体,但背景减除是最常用的方法。自适应背景模型用于创建均值漂移跟踪技术,本文展示并实现了该技术。在这种情况下,背景模型逐帧提供和更新,因此,遮挡问题被完全消除。目标跟踪算法使用与目标识别算法相同的视频流进行工作。在 MATLAB 中,对这些工作进行了模拟,并使用基于图像和基于视频的指标对其性能进行了评估,以确定它们在实际应用中的表现如何。
