High dynamic range image processing have recently become an important topic in consumer electronics market. While multi-scale retinex with color restoration (MSRCR) have been well developed, disadvantages of low performance is not favorable to a mobile computer-vision system. To remedy the above problem, this paper proposes an accelerated MSRCR with effective use of ARM Cortex-A9 architecture and...
Recently, the fact that mobile devices with various kinds of hardware and software platforms constantly appear on the market has resulted in huge amount of mobile applications coming out based on different platforms. Thus a big challenge has emerged to design applications on the heterogeneous devices and operating systems (OSes). This paper proposes a completely cross platform mobile transparent computing...
Rooting process of wheat was modeled in use of Linden Mayer system in the present study. Rooting rules along with growth cycle were concluded based on topology and biology analysis, in which the seminal roots and crown roots were treated separately. Meanwhile, some easy-to-use key parameters which are agronomical meaningful were proposed, including time, size, orientation and so on. After these preparations,...
A high efficiency power management system for solar energy harvesting applications is proposed. The power management system receives power from photovoltaic (PV) cell and generate different voltage levels, they are 1V~0.3V for analog circuitry and low power digital circuitry, -1.2V for super-cutoff technique in memory circuitry, and 10V for FLASH memory or I/O components. The great voltage varieties...
The wireless smart camera networks is defined in this paper. Its system architecture, characteristics and application direction are introduced. And then, the key factors are analyzed in designing and developing of wireless smart camera network platforms. According to the mote architecture, the platforms are divided into two categories: detached platforms and combinative platforms, and are analyzed...
Mobile ad hoc networks (MANET) are characterized by low bandwidth, lossy links and by constant topology change. Many network management architecture and techniques were put forward to adapt to these environments. In this paper, an adaptive, free management architecture based on peer management domain was proposed, and a new method of peer management domain partition was mainly introduced, last a prototype...
