In the past decade, Location-Based Social Networks (LBSNs) have attracted attentions from both the academia and industry. All LBSN sites are venue-centric, i.e., each review or check-in must be associated with a venue. Despite the importance of the venues, there still lacks a systematical study on LBSN sites from the venues' perspective. To fill this gap, we conduct a comprehensive study on Dianping,...
Drivers' failure to observe traffic signs, especially the stop signs, has led to many serious traffic accidents. Video-based traffic sign detection is an important component of driver-assistance systems. In earlier systems, simple color and shape-based detection methods have been broadly applied. Recently, feature-based traffic sign detection algorithms are proposed to obtain more accurate results,...
TOPPERS Project is to develop a series of open source real time operating systems(RTOS) and other software stacks for embedded systems, also is one of the latest developments of ITRON specification, which is de-facto standard real time kernel specification in Japan. TOPPERS/ASP kernel is the core and foundation of TOPPERS Project, also is an exploration and protype of next generation RTOS. This paper...
A component based hybrid embedded framework for mobile robot is presented in this paper. There are 3 layers in this framework, data layer, real-time layer, and high performance layer. The hardware consists of a hybrid architecture of Advanced RISC Machine (ARM) architecture micro controller and Field Programmable Gate Array (FPGA) with high-speed parallel/serial bus. The software mainly includes a...
