In statistical pattern recognition, a Gaussian mixture model is sometimes used for representing the distribution of vectors. The parameters of the Gaussian mixture model are usually estimated from given sample data by the expectation maximization alg

For the preprocessing of shape recognition in computer vision, it is necessary to reconstruct a shape from 3D range data or 2D edge image data. Efforts have been made to approximate a shape-recovery problem by using a super second-order function or a

We propose a new cone-beam shift-variant filtered backprojection (FBP) method for non-planar orbit data acquisitions. The new method is exact, fast and stable to discretization errors. It is based on the hybrid FBP framework whose key feature is to c

New methods are proposed to localize multiple current dipoles from spatio-temporal biomagnetic data obtained with SQUID magnetometers. The proposed methods are based on subspace fitting (SF) and weighted subspace fitting (WSF) frameworks that have be

An edge-detection method based on Markov random field and statistical estimation is proposed. Compound Gauss-Markov random fields are used as the image model, and the edge-detection problem was formulated as the maximum a posteriori probability (MAP)

Statistical quantum noise is a major factor causing degradation in emission computed-tomography (ECT) images. The maximum a posteriori probability (MAP) estimation has been used to mitigate the noise problem with limited success. The two major shortc

Levan was produced by a newly isolated bacterium from soil, taxonomically identified as a Serratia sp. This is the first report of levan production by Serratia sp. The levan was digested by levanase, which cannot hydrolyze β-2,1 linkages and the rem

When Arthrobacter hyalinus was grown on isopropanol, a large amount of red pigment was accumulated in the culture broth. The pigment was isolated from the culture broth. With thin layer chromatography, FD mass, IR, 1 H-NMR, 13 C-NMR, and absorption s
