The interface for an industrial real-time detecting system is described. The operation of the system, hardware and software design of the interface are discussed with the input image and processing image of the system given.
In this paper the problems of image processing in welding process have been studied, for example, how to detect the edge position of welding seam and to ascertain the size and shape of welding pool and so on. The traditional method of image processing is sensitive to noise and other disturbances, so it is difficult to process images accurately and timely.
It has been tested using SPOT·HRV multispectral data. 9 cases have been used to evaluate the approach and the classification accuracies have been compared. As a result, PCC(Probability of Correct Classification) and the Division Accuracy are increasde respectively from 88.1% to 92.2% and 91.0% to 96.5%.
The first stage should be the selection of an appropriate color space and extracting the major color characteristics when describing and processing an image with computer.
While extracting feature points, the limitation to confirm threshold by tentative method according to some a priori information on processing image can be avoided.
A system for automated image processing is described, which is capable of processing image files in a batch-mode thus allowing high-throughput of microarray image analysis.
We therefore used image-intensified video-microscopy of the injected region and video processing (Image-1) of artifact-free regions, to greatly improve the consistency.
The computer has 128 MByte of RAM, and up to 700 live images can be stored in memory for quick post-exposure image processing (image selection and alignment).
The power coefficient of HFETR is defined and measured.On data handing,point reactor model of neutron kinectics is used.Variation of the reactor poweris considered as linear.The reactor power coefficient is calcuated in view of xenon effect.
A new method for pseudocolor density enoording is presented: phase modulation by sampling with a grating, bleaching the sampled plate and choosing the zeroth or first diffracyion order for white light illumination.
It has long been a difficult task to use old methods to estimate rapidly andsynoptically the primary productivity of sea waters. The satellite remote sensing datahas been used to analyse the chlorophyll--a content in the Huang Hai and Bo Hai Seasin this paper. It demonstrates that the correlation between the satellite-derived cont-ent and the measured content of the both seas in the same month seems very. close,i.e., the distribution pattern of chlorophyll--a agree with the accumulated knowledgefrom the pro...
本文根据黄、渤海航天遥感信息,将这两个海区的叶绿素 a 含量的遥感数据与同期实测数据进行了比较研究,求得两种数据的相关系数为 0.85。本文还对遥感原始处理图象作几何纠正,并将它转换成黄、渤海区叶绿素 a 含量分布线画解译图。并进一步应用真光层初级生产力的经验式,计算得到了黄、渤海23个水域的冬季初级生产力值。
