Abstract:

Video surveillance systems have been commonly used in transportation systems to support traffic monitoring, speed estimation, and incident detection. However, there are several challenges in developing and deploying such systems, including high development and maintenance costs, bandwidth bottleneck for long range link, and lack of advanced analytics. In this thesis, I leverage current wireless, video camera, and analytics technologies, and present a wireless traffic monitoring system. I first present an overview of the system. Then I describe the site investigation and several test links with

Abstract:

Automatic Face Recognition (AFR) can be useful in the forensic field when identifying people in surveillance footage. In AFR systems it is common to use deep neural networks which perform well if the quality of the images keeps a certain level. This is a problem when applying AFR on surveillance data since the quality of those images can be very poor. In this thesis the CNN FaceNet has been used to evaluate how different quality parameters influence the accuracy of the face recognition. The goal is to be able to draw conclusions about how to improve the recognition by using and avoiding certai

Abstract The last decade was marked by a set of harmful events ranging from economical crises to organized crime, acts of terror and natural catastrophes. This has led to a paradigm transformation concerning security. Millions of surveillance cameras have been deployed, which led to new challenges, as the systems and operations behind those cameras could not cope with the rapid growth in number of video cameras and systems. Looking at today’s control rooms, often hundreds or even thousands of cameras are displayed, overloading security officers with irrelevant information. The purpose of this

Abstract:

Small Unmanned Aerial Vehicles (SUAVs) are an attractive choice for many surveillance tasks. However, video from an SUAV can be difficult to use in its raw form. In addition, the limitations inherent in the SUAV platform inhibit the distribution of video to remote users. To solve the problems with using SUAV video, we propose a system to automatically create geo-referenced mosiacs of video frames. We also present three novel techniques we have developed to improve ortho-rectification and geo-location accuracy of the mosaics. The most successful of these techniques is able to reduce geo-locatio

Understanding customer experience in real-time can potentially support people’s safety and comfort while in public spaces.

Manual monitoring through surveillance cameras can enable organisation personnel to observe people.

碩士<br>國立雲林科技大學<br>電機工程系碩士班<br>93<br>The deterioration of social order, which causes vandalism and terrorism around the world, has increased the importance of security and raised the demand on surveillance system. Therefore, the improvement on the capability of surveillance system is currently attracting a great deal of attention. Although intelligent multi-camera surveillance systems have been developed for some time, most of the systems can not effectively achieve the goal of tracking and positioning in an indoor environment. A functional analysis found that the reason is due to mutual occlus

碩士<br>國立臺北科技大學<br>資訊工程系研究所<br>100<br>In current era, there are various kinds of sensor used to detect the occurrence of fire. When a fire disaster occurs, security needs to go to the place and assesses the situation. In contrast, video-based fire detection system not only gives a faster response time but also provides with some fire information. This information help security to verify the fire alarm. This study proposes a method to detect the little flame in the early stage of fire combustion. The foreground object was extracted by motion detection and YCbCr color clues. To avoid the noise of

碩士<br>國立臺北科技大學<br>電機工程系研究所<br>101<br>Among all the visual surveillance systems, most of the algorithms apply the so-called background subtraction approach for the detection of a foreground, i.e., for the detection of a moving target. However, the background subtraction approach is susceptible to making an incorrect judgment for a time-varying environment, such as the change of light source, the interference of waving trees, the change of shadow, and the texture caused by raindrops. To conquer this problem, some of the researches propose the use of a statistical approach for the construction of

As to the chosen of programs, an idea is made in this project to utilize Microsoft Visual C++ 6.0 as the interface software between the image processing system and the user. Images captured by camera are transferred to random-access memory of PC to perform image treatments and analyses. As to the system

These systems can find applications in fire emergency, security, smart home and agriculture. Recently, surveillance systems combining wireless sensor networks with inexpensive web cameras or high quality Pan-Tilt-Zoom (PTZ) cameras have become more and more popular. In traditional video surveillance systems, a number of video cameras are required in order to achieve a desirable system performance. Another shortcoming is that i
