MIGRATION ABILITY CALCULATION DEVICE, MIGRATION ABILITY EVALUATION METHOD, AND COMPUTER PROGRAM FOR CAUSING COMPUTER TO EXECUTE MIGRATION ABILITY EVALUATION METHOD

摘要

The first aspect of the present invention provides a migration ability evaluation method comprising: a trajectory generation step of generating a trajectory of movement of an object being observed of a living body on the basis of a plurality of images of the object being observed acquired by capturing observation images of the object being observed multiple times in a time-series manner; a migration ability calculation step of calculating a migration ability measure indicating the degree of migration of the object being observed in a certain direction on the basis of the trajectory of movement of the object being observed; and a migration ability evaluation step of evaluating whether or not the object being observed satisfies a predetermined condition on the basis of the migration ability measure of the object being observed.
