Maximum-likelihood parameter estimation for in vivo magnetic resonance spectroscopy using modified cost function. Method when exact number of components is unknown
Journal Article
Finger vein authentication system based on capture of moving images
TL;DR: This study proposes a hand waving finger vein authentication system, in which a hand-waving movie is captured with a camera, and a biometric feature is obtained by synthesizing some finger vein patterns extracted from the movie.
Journal ArticleDOI
Estimation of an image sampled by a CCD sensor array using a color synthetic method
TL;DR: In this method, each primary color image is interpolated from the sampled data of three primary color images, and the optimal interpolation function is derived by minimizing the error of estimation.
Journal ArticleDOI
Modeling Scatter in Multiple Energy Windows to Incorporate Scattered Radiation Information in Single Photon Emission Computed Tomography Imaging
TL;DR: In this paper, the authors investigated a method of modeling scatter in multiple energy windows in cases of a few projection views and analyzed the system performance using singular value decomposition and resolution kernels.
