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,...
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 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...
