In the present paper, an adaptive α-β filtering algorithm is adapted for the motion compensation of EIS(electronic image stabilization). It is characterized of less computation, and easy to be realized in real-time. Inter-frame global motion vectors were predicted by feature corners matching based motion estimation. The global camera motion was defined in terms of constant velocity motion models,...
For such an environment, such as radiation, pollution, dangerous, distributed environment where the staff is not easy to reach, it is difficult to complete data collection and real-time monitoring through the traditional manual method. The study of remote wireless monitoring system, which based on the MCU (micro control unit programming) and GPRS (General Packet Radio Service) architecture, can well...
In the remote, hazardous, distributed and external environment, such as radiation source, pollutant source and pipeline of petrol, water and gas, it is difficult to collect and send the necessary message in real-time by traditional monitoring ways. This paper briefly describes the design of remote wireless monitoring system based on MCU (Micro-programmed Control Unit) and GPRS (General Packet Radio...
MEMS(micro-electro-mechanical system) combining the micro-mechanical and the micro-electro technology gets a prominent development at the present time. Compared with the traditional mechanical, laser and fiber-optic gyro, MEMS gyro has some outstanding advantages including cheap, small volume, light, less power dissipation, quick start-up and shock resistance, so it's suitable for stabilization platform...
In the remote, hazardous, distributed and external environment, such as radiation source, pollutant source and pipeline of petrol, water and gas, it is difficult to collect and send the necessary message in real-time by traditional monitoring ways. In response to this demand, this paper presents the design of wireless remote monitoring system solution that is based on the GPRS(General Packet Radio...
In order to over the shortcoming of the incomprehensive of summarization, a new lexical-chain-based keywords extraction and automatic summarization algorithm from Chinese texts based on the unknown word recognition using co-occurrence of neighbor words is proposed in this paper, and an algorithm for constructing lexical chains based on Hownet knowledge database is given in the method, lexical chains...
In order to reduce the dimensionality of feature vector space and reduce the computing complexity of categorization, each document of the train set is summarized automatically and two approaches to text categorization based on these summaries are proposed: in the first approach, the text summarization is directly used for feature selection and categorization instead of the original text; in the second...
