There are some different methods used for depth perception. In this paper, a new method for the depth perception, by using a single camera based on an interpolation, is introduced. In order to find the parameters of the interpolation function, a set of lines with predefined distance from camera is used, and then the distance of each line from the bottom edge of the picture (as the origin line) ...

Interaction using depth-sensing cameras has many applications in computer vision and spatial manipulation tasks. We present a user study that compares a short-range depth-sensing camera-based controller with an inversekinematics keyboard controller and a forward-kinematics joystick controller for two placement tasks. The study investigated ease of use, user performance and user preferences. Tas...

Sophisticated video processing effects require both image and geometry information. We explore the possibility to augment a video camera with a recent infrared time-of-flight depth camera, to capture high-resolution RGB and low-resolution, noisy depth at video frame rates. To turn such a setup into a practical RGBZ video camera, we develop efficient data filtering techniques that are tailored t...

Depth of field is the swath through a 3D scene that is imaged in acceptable focus through an optics system, such as a camera lens. Control over depth of field is an important artistic tool that can be used to emphasize the subject of a photograph. In a real camera, the control over depth of field is limited by the laws of physics and by physical constraints. The depth of field effect has been s...

The Visual Internet of Things is an important part of information technology. It is proposed to strength the system with atomic visual label by taking visual camera as the sensor. Unfortunately, the traditional color camera is greatly influenced by the condition of illumination, and suffers from the low detection accuracy. To solve that problem, we build a new Visual Internet of Things with dep...

We present an approach for registering an aerial Digital Elevation Model (DEM) with a color intensity image obtained using a camera mounted on a mobile robot. An approximate measurement of the camera pose is obtained using auxiliary sensors on-board the robot. The DEM is transformed into a depth map in the camera’s coordinate system using this initial pose. The problem is now simplified to the ...

We present a new concept for the extension of epipolar image analysis to more general camera configurations like circular camera movements usually occurring for concentric mosaic acquisition. In this way the robust method for 3D scene depth reconstruction which we call Image Cube Trajectory Analysis (ICT) is no longer restricted to horizontal, linear, and equidistant camera movements. Similar t...

OBJECTIVE We aimed to estimate the accuracy of visual estimation of chest compression depth and identify potential factors affecting accuracy. METHODS This simulation study used a basic life support mannequin, the Ambu man. We recorded chest compression with 7 different depths from 1 to 7 cm. Each video clip was recorded for a cycle of compression. Three different viewpoints were used to reco...
