Moving object detection and tracking is the process of identifying and locating the class objects such as people, vehicle, toy, and human faces in the video sequences more precisely without background disturbances. It is the first and foremost step in any kind of video analytics applications, and it is greatly influencing the high-level abstractions such as classification and tracking. Traditional methods are easily affected by the background disturbances and achieve poor results. With the advent of deep learning, it is possible to improve the results with high level features. The deep learning model helps to get more useful insights about the events in the real world. This chapter introduces the deep convolutional neural network and reviews the deep learning models used for moving object detection. This chapter also discusses the parameters involved and metrics used to assess the performance of moving object detection in deep learning model. Finally, the chapter is concluded with possible recommendations for the benefit of research community.

This paper uses a deep learning model called Faster R-CNN to detect and track objects in images. Two backbone networks such as ResNet-101 and VGG-16 are tested on a self-created dataset and PASCAL VOC dataset. Intersection over union (IoU) technique is used for the purpose of object tracking. The impacts of batch size, number of iterations and learning rate are analysed. The paper finds that ResNet-101 outperforms VGG-16 significantly by 13% on test data. This finding reinforces that deeper network is better in feature extractions and generalizations. IoU is able to track multiple objects and can identify the loss of track. The processing of frames per second is found to be 5 fps. The study has implications for many computer vision applications. For example, the deep learning based object detection and tracking can either augment the capability of LiDARs and Sensors or become an alternative to them in self-driving vehicles.

Abstract. Currently, deployment of UAV has transformed from crucial to day-to-day scenarios for various purposes such as wastage collection, live entertainment, product delivery, town mapping, etc. Object tracking based UAV applications such as traffic monitoring, wildlife monitoring and surveillance have undergone phenomenal changeover due to deep learning based methodologies. With such transformation, there is also lack of resources to practically explore the UAV images and videos with deep learning methodologies. Hence, a deep learning-based object detection and tracking tool with UAV data (DL-ODT-UAV) is proposed to fill the learning gap, especially among students. DL-ODT-UAV is a resource to acquire basic knowledge about UAV and deep learning based object detection and tracking. It integrates various object annotators, object detectors and object tracker. Single object detection and tracking is performed with YOLO as object detector and LSTM as object tracker. Faster R-CNN is adopted in multiple object detection. With exploring the tool, the ability of students to approach problems related to deep learning methodologies will improve to a greater level.
