Abstract or Description
Discrete tomography deals with image reconstruction of an object with a finitely many gray levels (such as two). The strip-based projection model is more realistic to model the raw detector reading in some applications than the line-based projection models. In this talk we will analyze the linear system generated by the strip-based projection model and establish equivalence between the system matrices generated by the strip-based and line-based projection models. An algebraic algorithm for binary image reconstruction will be presented too. This new algorithm applies the singular value decomposition and the Moore-Penrose inverse of a rank modified matrix. Numerical experiments demonstrate the efficiency of our algorithm. This is a joint work with Dr. Jiehu Zhu at Georgia southern University, Prof. Yangbo Ye at University of Iowa, and Prof. Ge Wang at Virginia Tech.
