The main contribution of our method is that it allows for largely mismatched content between the adjacent views. To do this, we detect robust keypoints in each of the input images and match them between the adjacent views. Then the correct correspondences are employed to compute the projective matrix through least-square method. After aligning the inputs on the same plane, we use a weight mask to blend the overlapped views with different priorities. This blending strategy keeps the main information of the scene and avoids the interference of the mismatched inputs. We demonstrate the effectiveness of our method on image sets with large misregistration.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115809598","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}

It has been observed that compression techniques works well, when repetition rate of the same symbols within the data are high i.e. when the redundancy within the data increases. During both encoding and decoding process, the online building of the dictionary in the primary memory ensures the single pass over the data, and the dictionary need not need to be transmitted over the network. Since this proposed technique scans the data byte-wise, hence chances of repetition of individual symbols is higher for text messages as we have limited number of key characters (0-127). Fixed length coding is simple to implement, as it transmits fixed length codes for all dictionary entries. Although for bigger messages better optimization in terms of size reduction can be achieved through variable length coding with L-Z technique, where transmitted code length corresponding to individual dictionary entries will vary according to the requirement dynamically.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123634577","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}

ARMA is a popular method to analyze stationary univariate time series data. Stationarity checking, model identification, model estimation and model checking are usually four main stages to build an ARMA model and model identification is the most important stage in building ARMA models. However there is no method suitable for ARMA model that can overcome the problem of local optima, which is suitable for any ARMA model. The effectiveness of PSO Algorithm which is used to choose the parameters of ARMA Model automatically is tested for ARMA (2,2) model example. The identification of model ARMA(2,2): xt +0.1xt-1-0.2xt-2 = at+0.2at-1-0.5at-2. The simulation shows that the PSO-based model identification method can present better solutions than the MINIC model identification method.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125044209","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}

The algorithm can determine the necessary runtime to convergence of state with unknown channel parameters by using the sandwiched CFTP scheme distribution, which allows for perfect (exact) and independent sampling from the desired stationary state distribution of the fading channels with unknown statistics so as to lower the computation complexity.

It has been of great practical value and is worth to researching further to optimize sensors' locations and number for smart structures. For piezoelectric smart composite laminated plates, least square wavelet support vector machine (LS-WSVM) with wavelet kernel function is proposed to establish the performance function of damage detection, and then an improved genetic algorithm (GA) is applied to optimize the performance function. To enhance the algorithm speed, LS-WSVM adopted as parallel mode are combined with GA, that is, a parallel genetic algorithm integrated neural network is constructed to realize the optimal sensor placement corresponding to its primal sensor placement based on damage detection.
