This report presents work on the detection and tracking of people in digital images. The employed detection technique is based on image processing and classification techniques. The work uses an object detection process to detect object candidate locations and a classification method using a Self-Organising Map neural network to identify the pedestrian head positions in an image. The proposed tracking technique with the support of a novel prediction method is based on the association of Cellular Automata (CA) and a Backpropagation Neural Network (BPNN).

Traditional target detection pipelines involve two sequential steps: the formation of a range-profile or likely-image, and the classification of likely targets within that image. Although it has been shown that target tracking in the RaDAR image-domain can be unnecessarily noisy, with more accurate and efficient implementations involving a direct analysis of the measured wavefield, image formation remains a desirable output in many applications due to its highly descriptive and interpretable nature. In this paper, we outline a mechanism for formalizing and accelerating this procedure in

Includes bibliographical references (p. 98-104).<br>Many motion tracking systems average and integrate tracking measurements over a period of time in order to reduce the effects of device noise, external noise and other disturbances. The target (user) is likely to be moving throughout the sample time, introducing additional 'noise' (uncertainty) into the measurements. Without filtering, noise can cause small variations in the estimated tracking positions (tracking drift) over time. There are many filters and algorithms that account for uncertainty due to noise.

Multi-pedestrian tracking (MPT) is the task of localizing and following the trajectory of pedestrians in a sequence. Using an MPT algorithm is an important part in preventing pedestrian-vehicle collisions in Automated Driving (AD) and Advanced Driving Assistance Systems (ADAS). It has benefited greatly from the advances in computer vision and machine learning in the last decades. Using a pedestrian detector, the tracking consists of associating the detections between frames and maintaining pedestrian identities throughout the sequence.

Doing so naturally introduces extra complexity to the eye-tracking pipeline, so we highlight the advantages and disadvantages. Our results show that adding LSTM-cells to

In recent years, increasing demands on sports analytics have triggered growing research interest in automatic player tracking-by-detection approaches. Two prominent branches in this area are Convolutional Neural Network (CNN)-based visual object detectors and histogram-based detectors. In this thesis, we focus on a particular sub-domain: player tracking by detection in broadcast football games. To tackle challenges in this domain, such as motion blur and varied image quality, two different systems are proposed based on histogram and CNN respectively. With the help of transfer learning, the CNN

To achieve the full-time automated monitoring, identification or tracking targets through the visual techniques, no one needs to control the system of unmanned control weapons. However, most of the traditional monitoring systems are mainly based on the fixed cameras, and they are not suitable for the condition that the cameras move irregularly with the vehicles. In this thesis, we emphasize that it i

We present a simple architectural mechanism called dynamicinformation flow tracking that can significantly improve thesecurity of computing systems with negligible performanceoverhead. Dynamic information flow tracking protects programs against malicious software attacks by identifying spurious information flows from untrusted I/O and restrictingthe usage of the spurious information.Every security attack to take control of a program needsto transfer the programÂs control to malevolent code. Inour approach, the operating system identifies a set of inputchannels as spurious, and the processor t

<p>Today's consumer mobile platforms such as Android and iOS manage large ecosystems of untrusted third-party applications. It is common for an application to request one or more types of sensitive data. Unfortunately, users have no insight into how their data is used. Given the sensitivity of the data accessible by these applications, it is paramount that mobile operating systems prevent apps from leaking it.</p><p>This dissertation shows that it is possible to improve the soundness of dynamic information-flow tracking on a mobile device without sacrificing precision, performance, or transpar

碩士<br>國立交通大學<br>資訊科學與工程研究所<br>104<br>Open source project has been widely developed and released thanks to the rapid growth of the Internet. Many useful open source projects can be found on the Internet. However, using open source project might be insecure even though it provides all the source code. The reason is that for users who just want to use the program as a tool, they might not actually check the containing code. The execution behavior of the program might not be the same as you think. Hence, in this research, we propose an elastic information flow tracking framework based on source co

碩士<br>國立清華大學<br>資訊工程學系<br>102<br>One of the fundamental features of the Internet of Things (IoT) is the ability to track its users location over time as a way to provide service in the right context. While many localization and tracking techniques have been proposed using cameras and RF-based techniques,they are ultimately limited by the ability to deploy tracking infrastructure and cannot operate when outside coverage area. To overcome this limitation, we propose encounter-based cooperative tracking for proximity-enabled wireless nodes. These nodes, carried by the subjects being tracked, ro

As technology advances, the applications of wireless sensor network are widely deployed on many kinds of places, such as military-capturing, home-caring, to collect lots of sensing data for analyzing. We transform these data into useful information, and the commanders can adjust the strategy according to circumstances. We propose an object tracking method, predictive approaching method to improve the tracking rate we propose before. Target tracking is an importing issue to collect data from
