We are developing an endoscopic manipulator control system based on eye tracking, which uses pupil variation to improve control performance. In this paper, we propose a new approach for the control of camera zoom for an endoscopic manipulator using pupil variation, which has not been previously attempted. Before using pupil variation for the zoom function, we observed how pupil variation was related...
Introducing robots into the operating theatre has become more popular in recent decades. Surgical manipulators have been developed to assist in surgeries like a human assistant to facilitate the surgical procedures. In this paper, we present an eye-controlled interface for the surgeon to control this kind of robot based on eye-tracking glasses. In our approach, we use the monitor for providing the...
During underwater monitoring observations in shallow water for coastal environmental conservation, the sea is not always clear and waves and current make the observational situation difficult. Underwater monitoring is still conducted mainly by human divers. Therefore, underwater robotics or remotely operated underwater vehicles (ROVs) that can monitor from a human diver's perspective are considered...
Many types of multimedia can be used to accommodate information for pervasive communication. Messages may be injected into them by information hiding techniques and extracted for various purposes. Such multimedia with messages embedded are called message-rich multimedia. A new method for creating message-rich videos is proposed in this study for people to exchange messages by display-and-imaging operations...
Street light monitoring is a vital and inevitable process to avoid night time accidents, criminal activities and thefts etc., In existing systems, the monitoring of street lights rely on man power or sensors which are not reliable and time consuming. Further sudden failure of the lights during night is very difficult to identify manually. Hence, this paper presents a summary of our work on implementation...
Developing surveillance and monitoring systems can be quite challenging at times, since the systems should be designed with consideration of the environment to be monitored. Good surveillance systems need to have dynamic features, e.g. monitoring cameras that are mobile and can move around the area being monitored. One scenario that requires such mobile monitoring is the surveillance of a large building...
The custom to gaze at screens of PC and smart phones has become common in daily life and it causes increase the symptom of dry eye syndrome. The purpose of this study is to develop a new monitor system to catch an eye area by using a front camera of a tablet, to visualize the opening and closing rate of the blink and to reduce eyestrain and to alert dry eye syndrome. Then, the image processing techniques...
Sleep position is an important feature used to assess the quality and quantity of an individual's sleep. Furthermore, it is related to sleep disorders like sleep apnoea and snoring, and needs to be tracked in nursery homes to avoid pressure ulcers. Therefore, a gravity sensor attached to the chest is generally used to register body position during sleep studies. We suggest a non-intrusive and cost-efficient...
As the elderly population grows rapidly, many social problems arise. In order to help enhance the lives of the elderly, many applications and devices have been developed. However, they are still limited to certain situations and lack some ability for remote assistance. Therefore, we present a projector-camera based assistance device for the elderly. It takes advantage of projection AR technologies...
Surveillance footage has become an integral part of law enforcement as video cameras become ubiquitous, affordable and more reliable. Dynamic vision sensor (DVS) emerges as a new sensing technology that outsmarts existing static CMOS image sensors in vision-enabled traffic monitoring, assisted living and high-speed target tracking for its low latency, high temporal resolution and wide dynamic range...
The work in progress described in this paper has the objective to implement a beehive monitoring system to monitor essential parameters of a bee hive (such as temperature, sound, weight) and additionally including an image recognition algorithm to observe the degree of infestation with Varroa mites. Mites should be detected at the entrance and statistics about the degree of infestation should be made...
This paper presents a novel strategy for weed monitoring, using images taken with unmanned aerial vehicles (UAVs) and concepts of image analysis and machine learning. Weed control in precision agriculture designs site-specific treatments based on the coverage of weeds, where the key is to provide precise weed maps timely. Most traditional remote platforms, e.g. piloted planes or satellites, are, however,...
In this paper, we study full-view coverage in camera sensor networks, by exploiting their limited mobility of orientation rotation. We focus on the fairness based coverage maximization problem, i.e., how to schedule the orientations of the camera sensors to maximize the minimum accumulated full-view coverage time of target points. To solve this problem, we first try to reduce the space dimension of...
The tsunami of video services brings huge pressure on communication systems, especially on some bandwidth-limited scenarios like wireless networks. Represented by H.264, current video compression approaches can save the transmission bandwidth by reducing the intra- and inter-frame redundancy. However, the huge amount of video content redundancy (VCR) in the transmission is still existing. In this...
Robust automatic detection of moving objects in a marine context is a multi-faceted problem due to the complexity of the observed scene. The dynamic nature of the sea caused by waves, boat wakes, and weather conditions poses huge challenges for the development of a stable background model. Moreover, camera motion, reflections, lightning and illumination changes may contribute to false detections....
Fixed underwater observatories (FUOs) equipped with a variety of sensors including cameras, allow long-term monitoring with a high temporal resolution of a limited area of interest. FUOs equipped with HD cameras enable in situ monitoring of biological activity, such as live cold-water corals on a level of detail down to individual polyps. We present a workflow which allows monitoring the activity...
An efficient photoplethysmography imaging system and advanced algorithm for continuous monitoring of skin microcirculation was developed. The system comprises compact device and computer with software for visualizing of skin blood volume changes. The software is able to process high-resolution microcirculation amplitude maps in real-time. It was tested in clinical environment during the regional anesthesia...
Texture feature is an important feature descriptor for many image analysis applications. The objectives of this research are to determine distinctive texture features for crowd density estimation and counting. In this paper, we have comprehensively reviewed different texture features and their different possible combinations to evaluate their performance on pedestrian crowds. A two-stage classification...
Respiratory Rate (RR) is one of the key vital signs that is routinely monitored by medical professionals and health care providers. Remote monitoring of it helps in detecting several clinical conditions and low-cost sensors are needed in telemedicine. Most of the current day measurement systems for RR involve the use of sensors that are in contact with the subject, causing discomfort. In case of neonates,...
The number of people suffering from motor impairment is increasing as incidence involving limb injuries can easily happen. These injuries may be traumatic injuries, congenital deformities, neurological and arthritic conditions or regional pain syndrome. Some of these injuries need operative procedure, whilst others use interventive methods. Regardless of the treatment performed, a vital component...
