A coarsely-synchronized, easy to deploy, distributed RF sensor network using embedded USRP software-defined radios on a dedicated IP network was developed and tested. The goal was the evaluation of a simple network and signal observation synchronization strategy on measured physical signals for use with collaborative sensor spectral estimation algorithms. The hardware and software architecture of...
In recent years, much research has been devoted to the construction of public-private key pairs; on the other hand, few have synthesized the visualization of the producer-consumer problem. Given the current status of efficient archetypes, leading analysts famously desires the emulation of congestion control, which embodies the key principles of hardware and architecture. In our research, we concentrate...
In this paper, we propose a Mixed Signal Parallel Multi 1Dimensional Block Matching Algorithm (MSPM-1D-BMA) based motion estimation (ME) processor. In contrast to the typical 2Dimensional full search block matching algorithm (2DFSBMA), the MSPM-1D-BMA based ME processor will greatly reduce the number of data movements in between memories. We employ a voting algorithm in the proposed ME processor to...
In this paper, we present a novel face detection architecture based on the boosted cascade algorithm. A reduced two-field feature extraction scheme for integral image calculation is proposed. Based on this scheme, the required memory for storing integral images is reduced from 400 Kbits to 2.016 Kbits for a 160??120 gray scale image. The range of the feature size and location is also reduced so the...
According to the communication and control requirement of multi-channel Control Area Network(CAN) bus by the HLA simulation platform, this paper described a embedded PowerPC system based method of design and implementation of multi-channel CAN communication platform. The corresponding Linux multi-channel CAN device driver has also been developed. This flexible system can connect to different number...
As the advance of high quality displays such as light-emitting diode (LED), liquid-crystal-display (LCD) or laser TV, the importance of a real-time high dynamic range (HDR) data processing for display devices increases significantly. Many tone mapping algorithms are proposed for rendering HDR images or videos on display screens. The choice of tone mapping algorithm depends on characteristics of displays...
