In this paper we present a scalable multi-view video streaming system with client-side view interpolation. Most parts of the system have been shown to be able to perform in real-time, but never as a complete system. Even though our algorithms are not yet highly optimized, we show that running a complete multi-view streaming system video on consumer hardware is possible today. Since multi-view coding...
Autonomous driving is the next breakthrough in automotive industry. Although the current achievements are very promising we still envision applications in which a certain level of assistance from the remote operator would be required. The goal of the project is to realize a semi-autonomous driving platform prototype with low-latency control/command channel to the operator over the 5G wireless network...
This paper propose an autonomous landing method for unmanned aerial vehicles (UAVs), aiming to address those situations in which the landing pad is the deck of a ship. Fiducial marker are used to obtain the six-degrees of freedom (DOF) relative-pose of the UAV to the landing pad. In order to compensate interruptions of the video stream, an extended Kalman filter (EKF) is used to estimate the ship's...
Intraoperative thermographic imaging, associated with time-resolved data analysis, is used to identify and visualise functional areas and pathological tissue in brain surgery. In this contribution we propose a hardware-software system for real-time pre-processing, fusion, and analysis of concurrent infrared and whitelight recordings. As a proof-of-concept, a digital temporal filter is applied to the...
Navigation system of some camera devices such as robot could be done by measure the rotation of device's wheels and device's velocity. But in several cases, like device for rescue and surveillance, sometimes the device need to deal with an uneven surface that makes device's wheels slipped, impacting in navigation measurement. Fortunately, almost all of devices nowadays equipped with at least one camera...
This paper proposes a design of the procedure for interoperability between video surveillance systems and verifies whether these systems are interworked according to the designed interworking procedures. In order to verify the interworking procedure of video surveillance systems, we implemented interoperability verification monitoring system. Through implementation results, we prove that video surveillance...
In this paper example of architecture system for examination existing devices for visual perception of the environment in Advanced Driver Assistance Systems is analyzed and presented. An overview of modern testing techniques as well as the motivation for such a device development arises from the specific testing conditions, increased volume of testing embedded software and applied algorithms as well...
Semi-autonomous driving is a huge technological step, but it also introduces a range of new challenges. Real-time control, selection and development of hardware platform, data transfer and development of algorithms are just a small collection of technical challenges to fully take advantages of such a system. The focus of this paper is analysis of some aspects of semi-autonomous driving, the corresponding...
In recent years, there has been an increasing growth of using vision-based systems for tracking the players in team sports to evaluate and enhance their performance. Vision-based player tracking has high computational demands since it requires processing of a huge amount of video data based on the utilization of multiple cameras with high resolution and high frame rates. In this paper, we present...
Use of camera has increased among professionals and nonprofessionals in recent years and videos are being captured widely and wildly for information, knowledge, surveillance, adventures and memories. So these videos are highly vulnerable to suffer from translational and rotational noises. These noise are caused by multiple factors and it is difficult to remove all those causes. So digital video stabilization...
The paper presents a new method of vehicle speed estimation using image data processing. The presented method employs conversion of greyscale input images into binary form. Image conversion into binary form is based on small gradients in the input images. Contents of the obtained binary images correspond with traffic scenes presented in the input images. Vehicle speed is estimated on the basis of...
Recently, interest in contents utilizing 360 and Virtual Reality images is increasing. These images are generally transformed into Equirectangular projection and transmitted in a 2:1 ratio rectangular shape. However, this method causes distortion of the upper and lower parts of the 360 images which is widely spread. Furthermore, since the spread 360 images requires higher data rate, it is difficult...
The increase in the number of elderly motivates academic researchers to develop technologies that can ensure self-sufficiency in their lives. In this research, prototype of an inexpensive video monitoring system for the elderly using a single RGB camera proposed. In the process is divided into two, namely vision and event recognition module. For event recognition, we use a hierarchical description-based...
In automatic and image processing based wildfire smoke detection various spatial and temporal procedures are used to detect certain wildfire features. The final step is usually the classification procedure that finally decides if some detected phenomena represents wildfire smoke or not. In classification procedure various classifiers can be used, but as the system has to work in real time and usually...
This work implements a tracking algorithm using video streamed from a flying platform in order to follow a moving object. The platform consists of a low cost quadcopter with a Wi-Fi camera which sends compressed H.264 video to a ground station. The object to be followed was defined by a bounding box on a single frame. In order to identify the object, each video frame was processed using motion estimation...
The 3D extension of the High Efficiency Video Coding (HEVC) standard achieves large compression rates thanks to the addition of several tools to encode multiview and depth information on top of those available in HEVC. The use of such tools incur in a very large computational demand, which can be a serious problem in power and computationally-constrained devices and applications. However, not all...
The paper present the idea of an integrated video surveillance and access control system including controls and authorization at checkpoints, application controls for shift management, leave management, attendance, remote access and centralized backup management with converged IP network. The project is first of its kind being implemented in Bhutan to provide a layered security at critical locations...
Information and Communication Technology is always walking in the forefront of human education. Now, it is the stage where human education has to adapt itself to the developing technologies. In 2016, the Natural Science Foundation suggested that people need to use the human-technology to improve and extend the human learning. This paper provides the concept of Software Defined Class (SDC), where the...
This paper describes a distributed multi-user video analytics platform supporting multiple video providers and multiple analytics. Scalability, portability, adaptability and resiliency are the objectives of a well-integrated video analytics platform. Being an integrated system of systems comprised of various resource nodes, the challenges in building such an infrastructure ranges from efficient system...
Wireless Multimedia Sensor Networks (WMSN) are one of the emerging paradigms of the Internet of Things (IoT) that are used to retrieve content including scalar data, video and audio streams and still images from the physical environment. In contrast to scalar sensor (such as temperature and humidity sensor) nodes, multimedia sensor nodes capture high volumes of data and perform far more complex tasks...
