An electro-conjugate fluid (ECF) is a kind of dielectric fluid which produces a powerful flow (ECF jet) when subjected to high DC voltage. The ECF jet is a promising micro fluid power source for actuators and sensors including micro motors [4] [5], liquid rate gyroscope [8] [9] etc. However, these applications are developed upon trials and errors because the theory of the ECF flow has yet to be fully...
This study proposes a 3D shape measurement device based on an image scanner. The shape reconstruction method using the image scanner is one of the photometric stereo method which uses multiple parallel light sources, but our proposed method is applied to linear light sources. This method is constructed by several processes. First, we estimate an object shape using four images taken by two groups of...
In this study, we propose a method to estimate 3D shape, color and specular reflections of an object using an image scanner with multiple illuminations. In the first process, we estimate an initial shape of the object. Several scanned images taken by illuminations located on the circumference are used to estimate object shape by the photometric stereo using average images reducing the specular reflection...
This study proposes a method to recover 3D shape, color and specular reflections of an object from images taken by an image scanner which has multiple illuminations. The proposed method is constructed by two processes. First is the initial shape estimation and second is the iterative process to estimate the object shape, color and specular components. In this paper, we propose two methods for the...
Due to the limitation of wireless communication capacity, a camera sensor network will be easily congested and the perceived video quality considerably deteriorates, when all nodes generate and transmit high-quality video data. To tackle this problem, taking into account that not all video data are equally important from a viewpoint of surveillance or observation applications, our research group proposes...
Leaf area index within vegetated surface and its fractional area to a target pixel (fraction of vegetation cover) are two important factors for estimation of cooling potential by green vegetation in the context of mitigating heat island effects. This paper explains a technique to retrieve these two parameters from satellite images utilizing three bands of visible, near-infrared, and shortwave infrared...
