In this paper we introduce the extendable and cross-platform software framework JULIUS, which will become public available by the end of this year. JULIUS consists of three conceptual layers and provides diverse assis...
详细信息
Intensity-based registration of dynamic imaging data (for example for motion correction of contrast-enhanced MRI) or multi-modal fusion requires the use of a correlation measure that has good photometric invariance pr...
