Conference on Medical Imaging - Image Processing
作者: Li, Siqi Wang, Guobao Univ Calif Davis Med Ctr Dept Radiol Sacramento CA 95817 USA
Image reconstruction for positron emission tomography (PET) is challenging because of the ill-conditioned tomographic problem and low counting statistics. Kernel methods address this challenge by using kernel represen... 详细信息

Conference on Internet Multimedia Management Systems II
作者: Wu, P Manjunath, BS Univ Calif Santa Barbara Dept Elect & Comp Engn Santa Barbara CA 93106 USA
A practical method for creating a high dimensional index structure that adapts to the data distribution and scales well with the database size, is presented. Typical media descriptors, such as texture features, are hi... 详细信息

Conference on algorithms and Technologies for Multispectral, Hyperspectral, and Ultraspectral Imagery XIII
作者: Johnson, Steven E. Eismann, Michael T. AF Inst Technol Wright Patterson AFB OH USA Air Force Res Lab Wright Patterson AFB OH USA
An algorithm called the constrained signal detector (CSD) was recently introduced for the purpose of target detection in hyperspectral images. The CSD assumes that hyperspectral pixels can be modeled as linear mixture... 详细信息

Conference on Medical Applications of Radiation Detectors V
作者: Bray, Iliana E. Tsai, Stephany J. Jimenez, Edward S. Sandia Natl Labs Albuquerque NM 87185 USA
Although there have been great strides in object recognition with optical images (photographs), there has been comparatively little research into object recognition for X-ray radiographs. Our exploratory work contribu... 详细信息
