This system is composed of the frontal network camera and the remote monitoring client. Firstly, it introduces the whole system structure design and the definition of functions. This embedded web camera takes the powerful ARM9 chip as MPU. The camera captures the video through embedded multitask operating system and the digital video has been compressed by the JPEG algorithm. The general users ...

In this paper, a feature-based technique for the camera pose estimation in a sequence of wide-baseline images has been proposed. Camera pose estimation is an important issue in many computer vision and robotics applications, such as, augmented reality and visual SLAM. The proposed method can track captured images taken by hand-held camera in room-sized workspaces with maximum scene depth of 3-4...

Fundus photography in adults and cooperative children is possible with a fundus camera or by using a slit lamp-mounted digital camera. Retcam TM or a video indirect ophthalmoscope is necessary for fundus imaging in infants and young children under anesthesia. Herein, a technique of converting and using a digital video camera into a video indirect ophthalmoscope for fundus imaging is described. ...

This paper describes a new approach to visualization of scenarios within the use case-based engineering of functional requirements – the so-called Video Camera metaphor. The Video Camera metaphor facilitates involvement of business people, customers, problem domain experts and other non-technical stakeholders into capturing and validating formal requirements models. The key tool, supporting the...

In this paper, we propose a content based video categorizing method focusing broadcasted sports videos using camera motion parameters. We define two new features in the proposed method; "Camera motion extraction ratio" and "Camera motion transition". Camera motion parameters in the video sequence contain very significant information for categorization of broadcasted sports video, because in mos...

Many conventional security systems use visual information from a video camera. However, these systems may not be able to acquire the important scenes in the blind area of the video camera. Acoustic security systems can support conventional visual security systems with acoustic events detection. In our research, we focused on acoustic security systems in the near field, and we designed a prototy...

In this paper, we propose a new scheme to generate multi-view video-plus-depth using a hybrid camera system, which is composed of one depth camera and multiple video cameras. In order to create the threedimensional (3-D) video, we first calculate the initial disparity for each view by projecting depth camera data onto each video camera using 3-D image warping. Then, a stereo matching algorithm ...

While video images are currently considered as two-dimensional (2D) entities, a recent trend is to extend video towards a 3D representation. In current video-coding algorithms like MPEG-4, global camera-motion is described as a set of abstract parameters, which have no direct relation to the physical camera movement. To bring physical meaning to these parameters, we present a new algorithm for ...

this paper presents a new methodology for the automated inspection of pipes. standard inspection systems are based on closed-circuit television cameras which are mounted on remotely controlled robots and connected to remote video recording devices. the main problems of such camera-based inspection systems are: 1) the lack of visibility in the interior of the pipes and 2) the poor quality of the...
