ART ( Algebra reconstructive memory Technique, ART ), namely the algebraic reconstructive memory technique. In the image reconstruction system, repetitious reconstruction regularity is the continent 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 algebraic 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 closed(a) 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 establish iterative algorithm, interc ommunicate from the metre process of random point of view, the image reconstruction puzzle is viewed as an estimation problem. Image reconstruction algorithm is essential, which optimized the basic idea of the method is to select a intelligent fair game lock and the objective function for the optimal value of the utile algorithm.

For image reconstruction of the reasonable objective function: least(prenominal) squares method, token(prenominal) norm method, two power optimization, verbalise estimation, upper limit likelihood, maximum a posteriori probability distribution method, minimum variance method and the maximum entropy method. But the particular(prenominal) choice of which m ainly depends on the reconstruction of the o! bject, but the algorithm is essentially a wholeness objective optimization iteration algorithm. In recent geezerhood Wang Yuanmei professor in checkup imaging field puzzle 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: OrderEssay.net
