In direct seeding systems, soil strength variability and crop residues increase the difficulty of seeding operation. Especially when trying to achieve uniform seeding depth that will result in reliable seed germination and plant emergence. An advanced improvement has been accomplished using direct seeding systems. However, some problems still exist in soil-machine interaction due to various rea...

World Health Organization estimates that 80% of the world population is affected of back pain during his life. Current practices to analyze back problems are expensive, subjective, and invasive. In this work, we propose a novel tool for posture and range of movement estimation based on the analysis of 3D information from depth maps. Given a set of keypoints defined by the user, RGB and depth da...

This paper proposes a novel reliable solution, named KinRes, to extract contactless respiratory signal via an IR-3D Depth sensor (Microsoft Kinect 2) on human subjects interacting with a computer. The depth sensor is very sensitive to the minor changes so that the body movements impose noise in the depth values. Previous studies on contactless respiratory concentrated solely on the still laid s...

In this paper we address the challenging problem of recovering the depth of a scene from a single image using defocus cue. To achieve this, we first present a novel approach to estimate the amount of spatially varying defocus blur at edge locations. We re-blur the input image and show that the gradient magnitude ratio between the input and re-blurred images depends only on the amount of defocus...

Obstacle detection and classification in a complex urban area are highly demanding, but desirable for pedestrian protection, stop & go, and enhanced parking aids. The most difficult task for the system is to segment objects from varied and complicated background. In this paper, a novel position-based object segmentationmethod has been proposed to solve this problem. According to the method prop...

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,...

Five experiments were conducted to investigate a proposal by Butler, Kang, and Roediger (2009) that congruity (or fit) between target items and processing tasks might contribute, at least partly, to the mnemonic advantages typically produced by survival processing. In their research, no significant survival advantages were found when words were preselected to be highly congruent or incongruent ...

Maymin (1987) proved that for binary systems the path-cut lower bound is sharper than the minimax lower bound when the components are all highly reliable, which was originally conjectured by Barlow and Proschan (1981). This motivates us to consider the problem that whether this property for binary systems remains valid for the more general and complicated multistate systems. An example is const...

As Web Services have matured the interactions that the services have between themselves have gotten increasingly complex and sophisticated. Web services can be composed easily from other services, and these services can be made to orchestrate with each other in dynamic fashion. As web services have become dominant in the Internet and Grid systems landscape, a need to ensure guaranteed delivery ...

In this paper, consideration is given to the validity of “statistical science”, which is necessary for innovation of the development designing process, for use in a new issue involving numerical simulation technology (CAE) in development designing. This new application of statistical science is designed to aid the transition from the “prototype / experimental based real machine evaluation metho...
