A reduced-order relaxation method, involving forward/backward integrations, for finding the solutions to the nonlinear two-point boundary value problems specified by the necessary conditions, including generation of initial controls, is presented.

The authors discuss the use of Kalman filtering theory for tackling the problem of high resolution image reconstruction from undersampled discrete frames, where each frame is shifted with respect to a reference frame, possibly degraded by a blur and also corrupted by additive noise. The results of computer simulations for the case where the input frames are blurred by identical six-pixel motion blurs are presented. Input images have 32×32 pixels and are generated by undersampling the blurred image. The reconstructed images have 64×64 pixels, and the various cycles of reconstruction are shown. Computer simulations for the case where the (independent) frames are blurred by independent motion blurs are considered. Conclusions are drawn with respect to the speed of convergence that can be inferred from the results of simulation","PeriodicalId":259801,"journal":{"name":"1990 IEEE International Conference on Systems Engineering","volume":"10862 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129912657","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}

With this approach, not only will the number of computations during training decrease, but also the problem of trapping in a local minimum will be minimized.

The procedure is generated from the parts geometry and topology model, and thus explicit specification of mating relations between parts is not required. The approach also prevents wrong mating relations from being presented and makes checking for validity unnecessary.
