Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING SYSTEM, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/137745
Kind Code:
A1
Abstract:
An image processing device according to the present invention comprises: a first classification means which classifies a plurality of pixels in two-dimensional image data constituting first three-dimensional image data including an object into a first class group by means of a trained classifier; and a second classification means which classifies, on the basis of the classification result by the first classification means, a plurality of pixels in second three-dimensional image data including the object into a second class group including at least one class of the first class group. According to the image processing device of the present invention, it is possible to reduce the burden on the user of giving pixel information and extract a region with high accuracy.
