Fusing Uncertain Structured Spatial Information [chapter]

Florence Dupin de Saint-Cyr, Robert Jeansoulin, Henri Prade
2008 Lecture Notes in Computer Science  
Spatial information associates properties to labeled areas. Space is partitioned into (elementary) parcels, and union of parcels constitute areas.  ...  In fusion problems, information coming from distinct sources may be expressed in terms of different conceptual and/or spatial ontologies, and may be pervaded with uncertainty.  ...  Spatial information may involve a mix of numeric and symbolic attributes, using different vocabularies more or less structured, but rarely unstructured.  ...

2019 IEEE Access  
As for the image fusion rule, the defined importance of image coefficients is used to combine the decomposed two-scale components to produce the final fused image, which could keep more spatial resolution  ...  Algorithm 1 could extract structural information while reducing the noise from the MRI image. Algorithm 2 is for averaging the color information from the PET image.  ...  On the other side, the smaller σ means the more spatial detail information of the structural information. The scale factor is used to balance structural information and white matter.  ...
