报告简介：

A new method is presented to calculate state space realizations of a three-dimensional (3D) image set. It is based on interpreting the image set as the impulse response of a 3D separable system. The proposed realization algorithm consists of two parts:

1.) Decomposition of a 3D image set into the product of three 1D components;

2.) Balanced state space realizations of finite 1D sequences.

The proposed method can be used for realizing the given 3D images exactly or approximately. The advantage of the method is noise can be reduced with little degradation on the image quality. It has been successfully applied in noise reduction of various 3D image sets of fluorescently labeled cells acquired by a fluorescent microscope. It can be used for noise reduction in a 3D image set or for noise suppression of a point spread function (PSF) which is an essential component in any 3D deconvolution algorithms.
