1. An image processing apparatus comprising:
at least one memory storing instructions; and
at least one processor that, upon execution of the stored instructions, are configured to:
detect, from an image in which an object including a plurality of parts is captured, first feature points corresponding to the parts of the object;
acquire a reliability indicating a likelihood that a position indicated by a feature point is a part corresponding to the feature point for each of the first feature points detected;
detect a second feature point based on some of the first feature points for a part corresponding to a first feature point with the low reliability; and
determine an area including the object based on some of the first feature points and the second feature point.
