Monitored 3-Dimensional (3D) video experience can be utilized as “feedback information” to fine tune the service parameters for providing a better service to the demanding 3D service customers. The 3D video experience which includes both video quality and depth perception is influenced by several contextual and content related factors (e.g., ambient illumination condition, content characteristi...

In this paper, an efficient depth-aware image enhancement system is presented. The depth information and well-known depth-cue relative perception are used to enhance 2D still images or videos. Image enhancement has been developed for decades in a lot of fields. However, conventional approaches deal with images in the 2D(x-y) projective plane. The information of z-axis is not used. In this work,...

3D measurements can be recovered from several views by triangulation. This paper deals with the problem of where to place the cameras in order to obtain a minimal error in the 3D measurements, also called camera network design in photogrammetry. We pose the problem in terms of an optimization design, dividing it into two main components: 1) an analytical part dedicated to the analysis of error ...

The solar wind serves as a laboratory for investigating magnetohydrodynamic turbulence under conditions irreproducible on the terra firma. Here we show that the frame work of Hall magnetohydrodynamics (HMHD), which can support three quadratic invariants and allows nonlinear states to depart fundamentally from the Alfvénic, is capable of reproducing in the inertial range the three branches of th...

This paper presents a new multi-passive-sensor target tracking algorithm which yields a nonlinear state estimator called Gaussian filter based on deterministic sampling. Firstly, this state estimator employs a deterministic sample selection scheme, where a parametric density function representation of the sample points is employed to approximate the cumulative distribution function of the prior...

Privacy requirements are difficult to elicit for any given software engineering project that processes personal information. The problem is that these systems require personal data in order to achieve their functional requirements and privacy mechanisms that constrain the processing of personal information in such a way that the requirement still states a useful functionality. We present privac...

exogenous enzymes such as xylanase can cause recovery of efficiency in poultry. in this study we investigated the effects of xylanase supplementation on small intestine histomorphometry in broilers chicken. two levels of xylanase supplementation (with or without 0.07% xylanase) was used in 4 treatment groups (two repetitions for each group and 15 chicks per group). after 42 days, 10 chicks from...

The NFC wallet is more popular in the world than before. Many people want to have a convenient payment in shopping, so the NFC wallet becomes an excellent choice for them. The NFC wallet uses the Card Emulation mode to achieve the transaction process. However, the Card Emulation mode does not have the specified secure transaction protocol. Our research provides a secure transaction protocol for...

A single two dimensional (2D) image does not contain depth information. An infinite number of points in the three dimensional (3D) space are projected to the same point in the image plane. But a single 2D image has some monocular depth cues, by which we can make a hypothesis of depth variation in the image to generate a depth map. This paper proposes an interactive method of depth map generatio...
