In recent years, road markings detection has received great attention and has been widely explored due to the aim of producing a system that is able to detect various shape of road markings on the images that are captured under various imaging conditions. Generally, the road images are captured using a camera, which has been placed inside the vehicle at a fixed position. However, the quality of the...
We developed a life support system for connecting PC with the real world. This system has seamless interface between the personal computer (PC) world and the real world, we have been studying a method for teaching a caregiver robot and a caregiver person. The interface proposed here allows a user to intuitively direct a robot's motion via a graphical user interface of the sort typical in the PC world...
Recently, support vector ranking has been adopted to address the challenging person re-identification problem. However, the ranking model based on ordinary global features cannot represent the significant variation of pose and viewpoint across camera views. Thus, a novel ranking method which fuses the dense invariant features is proposed in this paper to model the variation of images across camera...
Image filtering has long been an area of interest in computer vision applications. It may be used in applications where noise is prominent or when certain features need to be enhanced. While single-image filtering techniques are well-established in literature, the introduction of additional information can further improve the quality of filtering. Guided filtering allows for the use of additional...
With the technology today, detection of pedestrian was introduced to decrease the accidents in the roads. It was implemented on the traffic lights and cars. In this paper, integration of face detection and pedestrian takes place on the device called Raspberry Pi. OpenCV was used for the detections and programmed in Python. The webcam was used to capture images in real-time. The images was processed...
In this study, we estimate gaze direction using the relationship between the face and eyes. The face and eyes are divided laterally and in lengthwise direction. We set up an object laterally and in lengthwise direction and measured the face angle using a Kinect sensor, which is range image sensor, when gazing at an object. The angle of the eyes is fixed at the angle of the object and grasp of the...
Conventionally small area topographic detail plan is produced using land survey techniques. Various method of modern topographical detail plan however required more cost to speed up the data acquisition process for large data and high accuracy. The recent development in commercial grade Unmanned Aerial Vehicle (UAV) has the potential to be used as a data capture equipment with low cost. In this study,...
Water is one of the most precious commodities around the world. However, significant amount of water is lost daily in many countries through broken and leaking pipes. This paper investigates the use of low and high resolution infrared systems to detect water leakage in relatively dry countries. The overall aim is to develop a non-contact and high speed system that could be used to detect leakage in...
The annual International Mechatronics Educational Project (IMEP) was set up as a cooperation between three European universities from The Netherlands, Germany and Belgium in 2013 and was held for the 3rd time in Spring 2015. IMEP 2015 started with a kick-off meeting in February and ended 17 weeks later with an assessment including a demonstration of the students' work. During the fifth and tenth week...
Extraction of information from an image acquired by real imaging systems is a difficult task, since the observed image may be degraded by blurring. In this paper, a framework for classification of blur in an image is presented and a technique for classification of blur using invariants is proposed. In this method, the blur classification is carried out without estimating the blurring function. The...
The usage of stereo-vision in Automobile, Automation, machine-vision, Infotainment etc. is growing these days enormously day by day. To design a stereo-vision camera, we need to know optimal vergence pose between two cameras as well as number of stereo-pairs required for calibration so that stereo-vision can yield dense disparity map, precise 3D reconstruction, higher stereo-calibration accuracy as...
Requirements for a system are often discovered during negotiation process, at the time when stakeholders of the system are thinking over their premises or backgrounds behind other stakeholders' requirements, rather than at the time when stakeholders thinking about their own requirements. Disagreements and conflicts between stakeholders are utilized as a driver to discover requirements for the system...
This paper is devoted to the peculiarities of application of small UAVs for commercial overhead imagery for mapping. The conditions for obtaining the conditioned material was considered for further photogrammetric post processing, recommendations for the flight, aerial photography, installation of the main and auxiliary equipment aboard was given. A review of the characteristics of aerial systems,...
In this paper, we aim to assess the accuracy as well as compare between the Microsoft Kinect™ version 1 and Microsoft Kinect™ version 2 with regards to the purpose of respiratory motion tracking. We find that both correlate well to an alternative method of respiratory motion measurement i.e. a respiratory belt, up to a distance of around 2 m. However, we find that the Kinect™ version 2 has a slightly...
Powered by the pervasive penetration of inexpensive mobile devices and relevant APP's into our daily life, QR codes have found a wide range of applications in recent years. Therefore, the processing of the images of QR codes (also referred to as QR images) is an important task. In this paper, we try to deal with the scenario wherein the QR code is printed or pasted (altogether also referred to as...
We explore the applicability of electron-multiplying CCD (EMCCD) cameras to the problem of speckle imaging, i.e. imaging through atmospheric turbulence by processing short-exposure images. Signal-to-noise ratio expressions are derived for image and power spectrum estimates obtained from conventional and EMCCD cameras. An unbiased estimator for the bispectrum from EMCCD data is derived. Bispectrum...
This paper proposes an Eye Gaze Tracking (EGT) technique using a single eye image that can be easily calibrated and mapped for Human Computer Interaction (HCI). The technique employs both geometric and trigonometric relationships to find a user's Point of Regard, followed by calculating user-dependent variables for final mapping onto a user interface (UI). Experimental results show acceptable accuracy...
In the field of undersea research, underwater vehicles usually carry camera systems for recording. The captured image or video often has two undesired characteristics: color distortion and low visibility. This is because that the light is exponentially attenuated while penetrating through water. Furthermore, the quality of attenuation is associated with the wavelength of spectrum. This paper simplifies...
Poor colour rendering characteristic of a low cost camera results in poor colour recognition, especially with images taken under non-white illumination. A simplified colour calibration process for a digital web cam to be used for indoor illuminance measurement, enabling automatic, realtime, simultaneous measurement of illuminance of an indoor space at multi-locations based on its video image is proposed...
Generally, template matching methods are very sensible to image orientation, rotation or the size of the template. However, there are known occasions, when they perform better then other keypoint-based techniques. This article demonstrates a massively parallelizable method to multi-scaled template matching. By implementing it sequentially on CPU and on GPU with a naive approach, the runtimes can be...
