So hyperspectral images can not only reflect the external characteristics of the object through the spatial information, but also reflect its internal qualities of the spectral information. Based on this advantage, hyperspectral imaging has been widely used in the quality detection of agricultural products. Firstly, this paper summarizes the application of different imaging modes under different conditions based on hyperspectral imaging. Then it sums up the methods of spectral preprocessing and their applications in hyperspectral systems, the multiplicative scatter correction, the standard normal variable, the savitzky-golay smoothing, median-filter and the spectral differential all can correct the spectrum effectively in diverse backgrounds. Again, in this paper some common methods of hyperspectral data reduction are summarized either, the methods of principal component analysis, partial least squares, optimum index factor, successive projection algorithm and load factor are all widely used in reduction of hyperspectral data in agricultural products, these methods mentioned above can decrease the data dimension by feature extraction or feature selection, not only to simplify the computational process but to optimize conclusions through reduce redundancy information.","PeriodicalId":376884,"journal":{"name":"2017 9th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"262 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116237277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Usually the on-board signal processor is customized for the satellite which it is implemented on, with high processing ability but also with high construction cost and difficulty of reconfiguration. Thus a reconfigurable on-board processor is required to fulfill the demand of more frequent and periodic configuration update. This paper presents a computing task allocation scheme based on general purpose processor, (GPP)-digital signal processor (DSP) signal processing system, in which GPP handles the generic algorithms such as channel coding, modulation, time and frequency synchronization while DSP is in charge of special mathematic operations. We first introduce a low earth orbit (LEO) orthogonal frequency division multiplexing (OFDM) satellite physical layer system as an example with an analysis of the system's calculation characteristics. After that, a computing task allocation scheme corresponding to the system is derived based on the computation characteristic of all the modules in the system. Finally, the processing time with and without the scheme algorithm is tested on a system consist of a PC and a DSP board. Experiment results show that the processing time of the DSP-GPP system is shortened using the proposed scheme, compared to the GPP-only system without the task allocation scheme.","PeriodicalId":376884,"journal":{"name":"2017 9th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132393333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the health degree evaluation system which reflects the relationship between service level and priority is sorted out on the basis of D5000 system hierarchy analysis. Secondly, the health score of the system is calculated by modular MapReduce framework. In the first level MapReduce, Map task reads data and splits task. Reduce task calculates second-level indicators by hierarchical of D5000 system. In the second level MapReduce, it summaries score of second-level indicators in order to get the score of system and give the system status. Meanwhile, the adaptive task scheduling method ensure the system load balancing. Finally, the experiment platform of health evaluation of D5000 system is established, and the health evaluation experiment is carried out by the data of D5000 system. The result shows that the proposed method improves the efficiency of health calculation.","PeriodicalId":376884,"journal":{"name":"2017 9th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"269 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122184239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
