Firstly  an equivalent numerical simulation model of CAN bus network is built to derivate the mathematical expression of media access control delay. Secondly  optimization measures are further proposed to improve the data communication real-time. At last  the optimization measures tested by experiments are proved to be correct and effective.

To render a full-color image  need an interpolation process commonly referred to as CFA demosaicking  is required to estimate the other two contributions for producing a full-color image. But  the noise in imaging sensors not only corrupts the color filter array  at the same time introduces artifacts during the color interpolation step and influence quality of images. In order to acquire high quality full-color images  adopt a sort of viable and effective interpolation algorithm based on gradient  at the time of removing the noise  reserve image border and detail information clearly. 2012 IEEE.   On hyperspectral remotely sensed image classification based on MNF and AdaBoosting (EI CONFERENCE) 会议论文  OAI收割 2012 3rd IEEE/IET International Conference on Audio, Language and Image Processing, ICALIP 2012, July 16, 2012 - July 18, 2012, Shanghai, China 作者:  Yu P.;  Yu P.;  Gao X. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 As an effective statistical learning tool  AdaBoosting has been widely used in the field of pattern recognition. In this paper  a new method is proposed to improve the classification performance of hyperspectral images by combining the minimum noise fraction (MNF) and AdaBoosting. Because the hyperspectral imagery has many bands which have strong correlation and high redundancy  the hyperspectral data are pre-processed by the minimum noise fraction to reduce the data's dimensionality  whilst to remove noise bands simultaneously. Then  we use an AdaBoost algorithm to conduct the classification of hyperspectral remotely sensed image. Experimental results show that the classification accuracy is improved and the time of calculation is reduced as well. 2012 IEEE.
