ART ( Algebra reconstructive memory Technique, ART ), namely the algebraic reconstructive memory technique. In the image reconstruction system, reiterative aspect reconstruction method is the definitive method for Gorden R. The algebraic reconstruction technique ( Algebra reconstructive memory Technique, ART ), and Gilbert P. The proposed joint iterative reconstruction algorithmic programic program ( Simultaneous algebraical Reconstruction Technique, SIRT ). The subsequent development of a variety of algorithms can be broadly divided into deuce categories: one is of two kinds of classical iterative correction, such as Eggerment P . B. ART in the Kacmarz iterative cash advance for set block unopen circuit, Censor Y and Herman G . R. To further its improvement for inconsistent block iteration, so that the classical iterative methods to devise a unified framework. Two by the Kashyap R L and Mittal M . C. Introducing optimization theory found iterative algorithm, interc ommunicate from the measuring stick process of random point of view, the image reconstruction enigma is viewed as an estimation problem. Image reconstruction algorithm is essential, which optimized the basal idea of the method is to select a intelligent verifiable lock and the objective function for the optimal value of the effective algorithm.

For image reconstruction of the reasonable objective function: to the lowest degree squares method, token(prenominal) norm method, two power optimization, verbalise estimation, maximal likelihood, maximum a posteriori probability distribution method, minimum varianc e method and the maximum entropy method. But! the particular(prenominal) choice of which mainly depends on the reconstruction of the object, but the algorithm is essentially a oneness objective optimization iteration algorithm. In recent years Wang Yuanmei professor in checkup imaging field entrust forward much touchstone image reconstruction theory. Algebraic reconstruction algorithm in order to improve the clearcutness and convergence speed, the scholars in the fair ATR reconstruction algorithm is presented based on...If you want to get a full essay, order it on our website: OrderCustomPaper.com
