Underwater imaging has become a staple tool used by scientists exploring the deep ocean. Advanced camera systems are able to combine quantitative measurements from in-situ sensors with qualitative imaging to provide high fidelity multi-dimensional datasets which can be used to support a wide range of science questions. This includes benthic characterization and mapping, identification of biota and...
In today's conditions, parents have to work for home economics. For this reason, it is not always possible for parents to meet their children's needs, to protect them from dangers and to help them. Parents agree with a fee-paying caregiver to ensure that their children's needs are provided. Looking after a child by a caregiver can create a variety of security problems for the mother and the father...
Respiratory rate during sleep is one of the important vital sign for home healthcare. Therefore, noncontact respiration monitoring method during sleep without uncomfortable feelings caused by sensor-insertion is needed. The purpose of this study is to develop the noncontact respiration monitoring method during sleep using only low priced web-camera. The innovative point is to adopt the bed cover with...
This paper presents an indoor navigation system using visible light communication, taking advantage of the lightning in a room to provide shoppers their current location and a path towards a searched item. The system requires simple low-cost infrastructure due to inexpensive LEDs. The receiver comprises a mobile application installed on the customer's smartphone. The LED-based indoor navigation system...
Camera calibration is essential for accurate computer vision, and automatic calibration of some extrinsic parameters is needed in case the camera is placed on a mobile platform. The pitch and yaw angles, which are the most likely ones to change as the vehicle moves, can be inferred from the image coordinates of the vanishing point (VP). In this paper we present an artificial neural network approach...
In an autonomous driving system, drift can affect the sensor's position, introducing errors in the extrinsic calibration. For this reason, we have developed a method which continuously monitors two sensors, camera, and LIDAR with 16 beams, and adjusts the value of their cross-calibration. Our algorithm, starting from correct values of the extrinsic cross-calibration parameters, can detect small sensor...
High risk of climbing coconut tree manually become the main reason to build coconut tree plucking robot, not only the abnormality of bone but also the risk of falling from the coconut tree. The coconut tree plucking robot is made with the hope for helping people to pluck coconuts at the coconut tree easily and safely. Coconut tree with its condition make the coconuts difficult to be detected using...
This paper presents a method for contactless pulse oximetry measurement by photoplethysmographic images (PPGI) technique. The Kalman filter is applied to reduce the low frequencies of PPGI signals. The method has characteristics that make it an innovation in the field. The patient does not have any contact with the measurement device, and the developed algorithm has a low computational requirement...
This paper demonstrates the development of a low cost thermal imaging camera as an alternative to the commercial models. This device consists on a long wave infrared sensor which captures the infrared reflection from the physical objects. Thermal imaging camera technology has provided relevant developments for security systems, being used in surveillance activities such as law-enforcement, home intrusion...
Steerable surveillance cameras offer a unique opportunity to support multiple vision applications simultaneously. However, state-of-art camera systems do not support this as they are often limited to one application per camera. We believe that we should break the one-to-one binding between the steerable camera and the application. By doing this we can quickly move the camera to a new view needed to...
Quantifying the performance of camera-equipped mobile devices is covered in this standard, with an emphasis on metrics and procedures appropriate to the types of sensors, lenses, and signal processing routines present on such devices. It is not intended as a general image quality standard for photographs produced by high-end dedicated cameras, e.g., DSLRs. Metrics include spatial frequency response,...
In this paper, a multilevel grey-scale visual coding scheme is proposed for data transmission from LCD screens to Android smartphone cameras. A computer equipped with an LCD screen acts as a data transmitter whereas the smartphones with cameras perform the task of receivers. The multilevel modulation of light intensities allows each visual symbol or dot to carry more number of bits, thus increasing...
Car automation and surveillance is an escalating trend in this decade. Smart Vehicle security is becoming an indispensable need as it makes it easier for the owners to ensure their automobile's safety wirelessly. The core elements in our system consists of a mini central processing unit, motion detecting sensor accompanied with a camera module and buzzer. Our security network can be used to monitor...
Energy balance is one component of weight management, but passive objective measures of caloric intake are non-existent. Given the recent success of actigraphy as a passive objective measure of the physical activity construct that relieves participants of the burden of biased self-report, computer scientists and engineers are aiming to find a passive objective measure of caloric intake. Passive sensing...
Vehicle collision avoidance and obstacle detection system is one of the most critical factor in the automotive field. In the present, most of the vehicles enable an alert system which acts as a safety feature for the passengers. In this work, advanced navigation system which detects and avoids the object, is used in autonomous vehicles to safely navigate through the path. This system detects the obstacle...
The article introduces in detail methods for evaluating movement response of small animals (specifically reptiles and amphibians) to changes in their body orientation. The camera subsystem of revolvable platform offering a record of anatomical angles of body segment movements in space. A gyro accelerometer system allowing for measuring angles of the platform orientation in space. A software has been...
Surveillance is a paramount problem for harbor protection, border control and security of various commercial facilities. It is particularly challenging to protect the vast near-coast sea surface and busy harbor areas from intrusions of unauthorized marine vessels, such as trespassing boats and ships. In our project, we present a state-of-the-art solution for ship intrusion detection using image processing...
The paper proposed a novel method to autofocus on object and capture photo at stable fashion. An object-detection based approach has been proposed to automatically generate pixel objectness to find the optimal focus point. The temporal information has been used to measure the stableness. Experiments show the proposed approach could enhance the photo quality taken on the mobile devices.
The excess of fatigue could result in someone's death. The result of questionnaire which author had distributed to 50 people that have work hourmore than 8 hour mentioned that 80% respondents detected to be fatigue, but from the percentage of the total, who consulted it to a doctor just as much as 5%. Intel, the giant microprocessor maker in the world, has made a camera that can capture image condition...
This paper presents an extrinsic calibration method of a camera and a laser range finder based on the automatic detection of the line feature. Firstly, a special 3D calibration target which contained four planes and five edges was projected, and then the visible image and laser data of the 3D calibration target could be obtained.
