Both the phenomena of the randomly occurring nonlinearity and the missing measurements are described by Bernoulli distributed random variables, where the occurrence probabilities could be uncertain. The event-triggered communication mechanism is introduced to save the network bandwidth during the data transmissions through the network. Additionally, the filter gain perturbations are characterized by employing the norm bounded uncertainties. The aim of the paper is to develop a robust event-triggered resilient filtering algorithm against the randomly occurring nonlinearity and missing measurements. Note that the analytical expressions of the filtering error covariance cannot be computed directly. Consequently, we derive its upper bound as an alternative way and subsequently minimize such an upper bound by properly designing the filter gain at each time step. Finally, an illustrative example is presented to show the effectiveness of the provided filtering algorithm.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":"21 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131992204","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}

In this paper, we propose a novel non-negative sparse discriminative low-rank representation algorithm (NSDLRR). First, we seek a sparse, low-rank and non-negative matrix in training samples. Then, we add a structural inconsistency constraint on this basis, make different kinds of samples as independent as possible, thereby increasing the extra recognition ability. Finally, the test samples are classified by sparse linear representation. Experimental results on different face database show that the algorithm has better performance.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132215633","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 state equation is obtained by building five order mathematical model, in order to reduce the correlation of data, data space is mapped to low dimensional subspaces via orthogonal transformations. Then, the Kalman prediction value is taken as the center of the observation signal which is processed by adding window processing, and the prediction value is gotten based on the PCA in the window. There are good stability and simple calculation in the algorithm.

This paper presents an appearance based loop closure detection algorithm based on bag of words method and inverse depth of feature words. Our proposed approach represent the feature points and descriptors in the images as the visual words according to the off-line generated visual directory to simplify the similarity comparison between the images. For the evaluation criteria, on the basis of tf-idf scores of visual words, the inverse depth of words are also introduced into the process of loop closure detection. Considering the temporal consistency of image sequences, the co-visibility graphs are also applied to verify the real loop from all candidates. At last, some experiment results are showed and analyzed to illustrate the feasibility and performance of our algorithm in different situations and environments.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":"27 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132359970","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}

Secondly, eliminating noise points and smoothing lane boundaries by using morphological erosion and opening operation in the binary image, then traversing the binary image and extracting the feature points. Then, the feature points are clustered by DBSCAN clustering algorithm, which are then divided into clusters.

Firstly, morphological noise reduction is carried out by using morphological weighting adaptive algorithm and then global optimization of OTSU image segmentation function is carried out by using improved genetic algorithm. The method can automatically adjust the genetic control parameters according to the individual fitness and the degree of population dispersion, which can speed up the convergence while maintaining the diversity of the population. Finally, the optimal threshold for image segmentation is obtained, which overcomes the poor convergence, premature and other issues of the traditional genetic algorithm. Experiments show that the threshold range obtained by the method is more stable, the calculation time of the threshold is greatly reduced, and the requirement of real-time image processing can be satisfied.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134064631","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}
