1. An image processing apparatus comprising:
one or more memories storing instructions; and
one or more processors that, upon execution of the stored instructions, are configured to:
detect a person in an input image;
detect a specific object in the input image;
detect an intermediate point in the input image based on a model configured to output an intermediate point between the person and the specific object;
specify, based on positional relationships between the detected person, the detected object, and the detected intermediate point, a combination of the detected person and the detected object indicating an identical person; and
determine a number of persons in the input image, based on the detected person, the detected object, and the specified combination.
