These can be obtained either through reconstruction of a model from measurements, or by directly modeling a virtual object, often on a real-world example. The former is often formalized as a regularized optimization problem, in which a data term ensures consistency between model and data and a regularization term promotes solutions that have high a priori probability. In this dissertation, different reconstruction problems in computer graphics are shown to be instances of a common class of optimization problems which can be solved using a uniform algorithmic framework. Moreover, it is shown that similar optimization methods can also be used to solve data-based modeling problems, where the amount of information that can be obtained from measurements is insufficient for accurate reconstruction. As real-world examples of reconstruction problems, sparsity and group sparsity methods are presented for radio interferometric image reconstruction in static and time-dependent settings. As a modeling example, analogous approaches are investigated to automatically create volumetric models of astronomical nebulae from single images based on symmetry assumptions.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Stephan Wenger\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3735742998\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783735742995\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bod - Books on Demand\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/02\/2014\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 198\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.53lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.27h x 5.83w x 0.42d","brand":"Stephan Wenger","offers":[{"title":"Paperback","offer_id":48217640698111,"sku":"9783735742995","price":20.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_e3e60cea-2cfa-433e-ac8b-6479ebc88a34.jpg?v=1771998498","url":"https:\/\/www.whiterainbookhouse.com\/products\/regularized-optimization-methods-for-reconstruction-stephan-wenger-9783735742995","provider":"WR Book House","version":"1.0","type":"link"}
