Over the last decade, there have been many studies that focus on modeling driver behavior, and in particular detecting and overcoming driver distraction in an effort to reduce accidents caused by driver negligence. Such studies assume that the entire onus of avoiding accidents are on the driver alone. In this study, we adopt a different stance and study the behavior of pedestrians instead. In particular,...
Multicolored Matrix (MCM) Code is a two-dimensional color coded matrix. It consists a sequence of images rendered at an optimum frame rate to transfer simple data between portable devices such as a mobile phone. We introduce an untried channel-less short range communication technology, designed with limitless storage capacity, great structural stability and flexibility due to which it can work in...
Due to the advancement in data capturing and different communication technologies, large amount of videos available to the viewers on different video sharing websites. Hence, complexity increases in finding the video with desired contents. For these applications, the videos are available in an elementary form called shots in the initial step. Detection of shots requires extraction of various features...
In this work, an autonomous surveillance system providing ultra wide angle (UWA) video information is presented using multi-UAV platform. Towards this end, a fleet of UAVs are initially deployed into appropriate formation (such as triangle, diamond, or line) with cameras pointing outwards to cover the region of interest (ROI). In aid of image processing technique, the UAVs formation will be further...
This paper presents a new approach for telepresence wheelchairs equipped with multiple cameras. The aim of this system is to provide effective assistance for the elderly and people with disabilities. The work explores the integration of the Internet of Things, such as multimedia, wireless Internet communication, and automation control techniques into a powered wheelchair system. In particular, multiple...
The article brings up the problem of tool support for the processes of learning and practical activities of surgeons using modern capabilities of information and telecommunication technologies. It discusses problems arising in the training of surgeons manipulating in the operating field of small dimensions, and similar problems of surgical care in a sparsely populated areas. The authors analyze the...
In this paper, we design an autonomous flight controller for height regulation and bang-bang controller for directional control of a light-weight flapping-wing micro air vehicle (FWMAV) with limited payload. We also present autonomous vision-based target tracking for a FWMAV equipped with a low-cost and light-weight first person view (FPV) camera. We construct a ground station, integrated with control...
This paper introduces the dangerous rock testing system based on FPGA technology research. This system will be the FPGA as the core, realize the function of the video image acquisition and image processing. The research of this system using the FPGA's excellent characteristics of high-speed processing, highly integrated is focused on judging and tracking to such as dangerous rock moving targets. The...
This paper presents the architecture and implementation of a tele-presence wheelchair system based on tele-presence robot, intelligent wheelchair, and touch screen technologies. The tele-presence wheelchair system consists of a commercial electric wheelchair, an add-on tele-presence interaction module, and a touchable live video image based user interface (called TIUI). The tele-presence interaction...
Video analysis is an essential process to segment and summarize sports videos automatically. In this paper, we propose fast and simple computer vision algorithms which can be employed to an event segmentation system for basketball broadcasting videos. In our approach, camera panning is estimated by the optical flow estimation and flow segmentation algorithms. For recognizing shot classes and clock...
Real-time video analysis at the edge of the network is very promising to significantly improve public safety, e.g., dangerous accidents detection and find a missing person. Simply uploading the video stream to the cloud for analysis costs too much energy and network bandwidth to an energy-limited camera. Hence we propose EVAPS (Edge Video Analysis for Public Safety), which distributes the computing...
Color space conversion is a basic and vital subject in digital multimedia procession. As VGA increasingly used in different field, it is important to convert video data to the data form that can show on VGA. In this paper, we design and implement a color space conversion system based on FPGA. Camera is used for capturing video then the captured YCbCr video data can be converted to RGB data after going...
We present a novel approach for real-time joint reconstruction of 3D scene motion and geometry from binocular stereo videos. Our approach is based on a novel variational halfway-domain scene flow formulation, which allows us to obtain highly accurate spatiotemporal reconstructions of shape and motion. We solve the underlying optimization problem at real-time frame rates using a novel data-parallel...
Traditional video synopsis methods model the processing into an optimization formula where relations among objects such as collision cost are utilized while entire re-calculation is introduced under each possible temporal shift. Unlike the pairwise cost optimization, we propose a low-complexity and efficient online synopsis method where each tube is processed independently. Without tubes' comparison,...
In recent years, the importance of location-based services and indoor positioning systems increased significantly for both, research and industry. Visual localization systems have the advantage of not depending on dedicated infrastructure and thus they are interesting for navigation within buildings. While there are already approaches which are using pre-recorded databases of reference images to obtain...

In this paper, we consider combinations of transmission schemes for each media in MVV-A (Multi-View Video and Audio) IP transmission when the total bitrate of transmitted audiovisual streams is regulated. We employ two types of transmission schemes: single stream transmission and all streams simultaneous transmission. We assess QoE of the four combinations of the transmission schemes by a subjective...
A FPGA-based embedded system development platform with dual-camera support, named MorFPGA Duo, is presented in this paper.

This research was carried out in order to use image processing techniques to detect, track, classify, and count vehicles in a real-time traffic video. Additionally this research also focuses on occlusion detection and handling, which involves detecting and handling the states when one vehicle superimposes the other or when two superimposed vehicles split, and lane categorization i.e. dividing the...
