Fingerprint preprocessing and recognition system development and design Qian Wu Weifang University of Science and Technology,shandong Weifang,262700,china; wuqian11111@163.com Keywords Fingerprint identification; Image processing; Image segmentation; Image enhancement Abstract: fingerprint image preprocessing and is one of the branch of image processing and pattern recognition, after several years of development the increasing maturity of the technology.
This is because on the one hand, for the protection of intellectual property rights and the interests of the business, the core of the fingerprint identification technology is only a few enterprises and institutions have; On the other hand, the people's growing material and cultural needs of the fingerprint identification system performance put forward higher requirements.

Study on the features of production decline law in oil manufacturing system in WangYao Block Qinghui Yan1,a Hanmin Xiao2,b Linghui Sun3 Weidong Liu3 Juncheng Hu4 1Institute of Porous Flow and Fluid Mechanics, Chinese Academy of Science, Langfang 065007,China 2Faculty of Petroleum Engineering, China University of Petroleum ,Beijing 102249，China 3Research Institute of Petroleum Exploration and Development-Langfang, Langfang 065007,China 4 CNPC Greatwall Drilling Company Engineering Institute, Panjin 124010,China aqinghuiyan1987@126.com bxiaohm69@petrochina.com.cn Keywords: low permeability, mid-high water cut stage, relative permeability curve, production decline, declining feature Abstract：Features of production decling determines the deployment of development project in oilfield, which has heavy influence on the oil manufacturing system.
Production decline equations have been deducted, which could be used to predict the declining trend in middle and high water-bearing period in WangYao Block, on the basis of material balance theory [8] and relative permeability curve.
