Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/241030
Kind Code:
A1
Abstract:
This image processing device is provided with a planar distribution acquisition unit which uses a plurality of radiation images captured using different radiation energies as input images and acquires an output image indicating a planar distribution of a substance included in the input images. When inputs are the input images, the planar distribution acquisition unit determines the output image from a likelihood and a prior possibility using the pixel value of a pixel of interest or the pixel values of surrounding pixels as inputs in such a way as to maximize the possibility that the output is the value of the planar distribution.
