Title:
主成分分析に基づく画像融合法
Document Type and Number:
Japanese Patent JP2014521945
Kind Code:
A
Abstract:
An image fusion method combines absorption, differential phase contrast and dark-field (scattering) signals obtained with X-ray phase contrast sensitive techniques, such as an arrangement of gratings. The process fuses the absorption and dark-field signals by principal component analysis. Further the differential phase contrast is merged into the PCA fused image to obtain an edge enhancement effect. Due to its general applicability and its simplicity in usage, the proposed process is usable as a standard method for image fusion scheme using phase contrast imaging, in particular on medical scanners (for instance mammography), inspection at industrial production lines, non-destructive testing, and homeland security.
