Download or read book Object Tracking Technology written by Ashish Kumar and published by Springer Nature. This book was released on 2023-10-27 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increase in urban population, it became necessary to keep track of the object of interest. In favor of SDGs for sustainable smart city, with the advancement in technology visual tracking extends to track multi-target present in the scene rather estimating location for single target only. In contrast to single object tracking, multi-target introduces one extra step of detection. Tracking multi-target includes detecting and categorizing the target into multiple classes in the first frame and provides each individual target an ID to keep its track in the subsequent frames of a video stream. One category of multi-target algorithms exploits global information to track the target of the detected target. On the other hand, some algorithms consider present and past information of the target to provide efficient tracking solutions. Apart from these, deep leaning-based algorithms provide reliable and accurate solutions. But, these algorithms are computationally slow when applied in real-time. This book presents and summarizes the various visual tracking algorithms and challenges in the domain. The various feature that can be extracted from the target and target saliency prediction is also covered. It explores a comprehensive analysis of the evolution from traditional methods to deep learning methods, from single object tracking to multi-target tracking. In addition, the application of visual tracking and the future of visual tracking can also be introduced to provide the future aspects in the domain to the reader. This book also discusses the advancement in the area with critical performance analysis of each proposed algorithm. This book will be formulated with intent to uncover the challenges and possibilities of efficient and effective tracking of single or multi-object, addressing the various environmental and hardware challenges. The intended audience includes academicians, engineers, postgraduate students, developers, professionals, military personals, scientists, data analysts, practitioners, and people who are interested in exploring more about tracking.· Another projected audience are the researchers and academicians who identify and develop methodologies, frameworks, tools, and applications through reference citations, literature reviews, quantitative/qualitative results, and discussions.

Book Synopsis Multiple Object Tracking Using Deep Learning Techniques by : Laia Prat Ortonobas
Download or read book Multiple Object Tracking Using Deep Learning Techniques written by Laia Prat Ortonobas and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This project has been devoted to (i) learning what Multiple Object Tracking (MOT) is, (ii) learning Python, one of the most used languages in Machine Learning and computer vision, and (iii) to evaluate a tracker (TrajTrack), currently being developed at the image processing group (GPI), against the UA-DETRAC dataset. The work has been divided in two parts. On the one hand, we have studied MOT and its main challenges, such as occlusions or identity switches, in order to follow multiple objects throughout a video sequence. To fully understand this problem, we have developed a multiple tennis ball tracker in Python from scratch. On the other hand, we have used TrajTrack, which is evaluated on a pedestrian dataset (MOT17), and adapted it to be evaluated against a car dataset (UA-DETRAC). For this, we have retrained the detection and re-identification models. We have obtained a 98.6% MOTA score for training and a 74.7% MOTA score for testing. These results are comparable with the state-of-the-art techniques.

Book Synopsis Data Association for Multi-Object Visual Tracking by : Margrit Betke
Download or read book Data Association for Multi-Object Visual Tracking written by Margrit Betke and published by Springer Nature. This book was released on 2022-05-31 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the human quest for scientific knowledge, empirical evidence is collected by visual perception. Tracking with computer vision takes on the important role to reveal complex patterns of motion that exist in the world we live in. Multi-object tracking algorithms provide new information on how groups and individual group members move through three-dimensional space. They enable us to study in depth the relationships between individuals in moving groups. These may be interactions of pedestrians on a crowded sidewalk, living cells under a microscope, or bats emerging in large numbers from a cave. Being able to track pedestrians is important for urban planning; analysis of cell interactions supports research on biomaterial design; and the study of bat and bird flight can guide the engineering of aircraft. We were inspired by this multitude of applications to consider the crucial component needed to advance a single-object tracking system to a multi-object tracking system—data association. Data association in the most general sense is the process of matching information about newly observed objects with information that was previously observed about them. This information may be about their identities, positions, or trajectories. Algorithms for data association search for matches that optimize certain match criteria and are subject to physical conditions. They can therefore be formulated as solving a "constrained optimization problem"—the problem of optimizing an objective function of some variables in the presence of constraints on these variables. As such, data association methods have a strong mathematical grounding and are valuable general tools for computer vision researchers. This book serves as a tutorial on data association methods, intended for both students and experts in computer vision. We describe the basic research problems, review the current state of the art, and present some recently developed approaches. The book covers multi-object tracking in two and three dimensions. We consider two imaging scenarios involving either single cameras or multiple cameras with overlapping fields of view, and requiring across-time and across-view data association methods. In addition to methods that match new measurements to already established tracks, we describe methods that match trajectory segments, also called tracklets. The book presents a principled application of data association to solve two interesting tasks: first, analyzing the movements of groups of free-flying animals and second, reconstructing the movements of groups of pedestrians. We conclude by discussing exciting directions for future research.
Book Synopsis Moving Objects Detection Using Machine Learning by : Navneet Ghedia

Available in PDF, EPUB and Kindle. Book excerpt: This book shows how machine learning can detect moving objects in a digital video stream. The authors present different background subtraction approaches, foreground segmentation, and object tracking approaches to accomplish this. They also propose an algorithm that considers a multimodal background subtraction approach that can handle a dynamic background and different constraints. The authors show how the proposed algorithm is able to detect and track 2D & 3D objects in monocular sequences for both indoor and outdoor surveillance environments and at the same time, also able to work satisfactorily in a dynamic background and with challenging constraints. In addition, the shows how the proposed algorithm makes use of parameter optimization and adaptive threshold techniques as intrinsic improvements of the Gaussian Mixture Model. The presented system in the book is also able to handle partial occlusion during object detection and tracking. All the presented work and evaluations were carried out in offline processing with the computation done by a single laptop computer with MATLAB serving as software environment.
Book Synopsis Deep-learning-based Multiple Object Tracking in Traffic Surveillance Video by : Liqiang Ding
Download or read book Deep-learning-based Multiple Object Tracking in Traffic Surveillance Video written by Liqiang Ding and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Multiple object tracking (MOT) is an important topic in the computer vision. One of its important applications is in traffic surveillance for examining potential risks for traffic intersections and providing analysis of road usages. In this thesis, we propose a powerful and efficient model for solving MOT problems under traffic surveillance environments. The model solves MOT problems with the strategy of tracking-by-detection, and is flexible in tracking 11 categories of common road users from various altitudes and camera pitches. Moreover, it is an end-to-end solution that removes need of any further processes. There is no manual labeling required in the initialization step and objects can be tracked regardless of their motion states, which makes it possible to be applied in a large scale. We validate our model with multiple challenging datasets and compare its performance with other state-of-art methods. The evaluation shows our model can deliver satisfying results even though a simple data association algorithm is utilized. Optical flow and discrete Kalman filter achieve competitive performances in extracting and predicting motion states of objects. However, there are not many methods available to combine them with deep learning models to solve MOT problems. Our proposed model achieves object detection with a pre-trained deep learning detector, and then performs data association based on optical flow vectors, object categories, and object spatial locations. In order to improve the accuracy, a combination of techniques such as Gaussian mixture modeling is employed. To handle occlusion and lost track problems, a Kalman filter is introduced to extrapolate the motion and spatial states of an object in the next frame, so that the model can still keep tracking for a certain number of frames. Our model recovers a tracking trajectory by connecting the tracklet to a new detection response if it has similar optical flow and the same category in a region of interest. We comprehensively examine both detection and tracking stages with multiple datasets. Our detector delivers comparable results to several state-of-art methods, but with a faster processing speed. The tracking algorithm was evaluated in a benchmark test along with a few state-of-art methods. Compared to them, our model delivers competitive accuracy scores and usually achieves the best precision scores. In addition, we assemble a novel customized traffic surveillance dataset which contains videos taken under various weather, time, and camera conditions, and qualitatively test our model against it. The results demonstrate that our model well handles crowded scenarios or partial occlusions by generating smooth and complete tracking trajectories. Using a simple yet effective data association algorithm together with a Kalman filter, it serves as a powerful solution for MOT problems." --

Book Synopsis Deep Similarity Metric Learning for Multiple Object Tracking by : Bonan Cuan
Download or read book Deep Similarity Metric Learning for Multiple Object Tracking written by Bonan Cuan and published by . This book was released on 2019 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple object tracking, i.e. simultaneously tracking multiple objects in the scene, is an important but challenging visual task. Objects should be accurately detected and distinguished from each other to avoid erroneous trajectories. Since remarkable progress has been made in object detection field, “tracking-by-detection” approaches are widely adopted in multiple object tracking research. Objects are detected in advance and tracking reduces to an association problem: linking detections of the same object through frames into trajectories. Most tracking algorithms employ both motion and appearance models for data association. For multiple object tracking problems where exist many objects of the same category, a fine-grained discriminant appearance model is paramount and indispensable. Therefore, we propose an appearance-based re-identification model using deep similarity metric learning to deal with multiple object tracking in mono-camera videos. Two main contributions are reported in this dissertation: First, a deep Siamese network is employed to learn an end-to-end mapping from input images to a discriminant embedding space. Different metric learning configurations using various metrics, loss functions, deep network structures, etc., are investigated, in order to determine the best re-identification model for tracking. In addition, with an intuitive and simple classification design, the proposed model achieves satisfactory re-identification results, which are comparable to state-of-the-art approaches using triplet losses. Our approach is easy and fast to train and the learned embedding can be readily transferred onto the domain of tracking tasks. Second, we integrate our proposed re-identification model in multiple object tracking as appearance guidance for detection association. For each object to be tracked in a video, we establish an identity-related appearance model based on the learned embedding for re-identification. Similarities among detected object instances are exploited for identity classification. The collaboration and interference between appearance and motion models are also investigated. An online appearance-motion model coupling is proposed to further improve the tracking performance. Experiments on Multiple Object Tracking Challenge benchmark prove the effectiveness of our modifications, with a state-of-the-art tracking accuracy.
