Document Type and Number:
WIPO Patent Application WO/2017/169397
Kind Code:
A1
Abstract:
[Problem] To determine a convergent point of motion of cells, and also to determine the strength of convergent motion. [Solution] The image processing device according to the present invention is provided with: a motion vector acquisition unit that acquires motion vectors at a plurality of locations within an image; an evaluation value acquisition unit that acquires an evaluation value representing the strength at which the plurality of motion vectors converge to a given point of interest; and a convergent point extraction unit that extracts, from among the points of interest on the basis of the evaluation value, a convergent point to which the motion vectors converge. This configuration enables determining of a convergent point of the motion of cells, and also enables determination of the strength of convergent motion.
