Image processing apparatus, image processing method, and non-transitory computer-readable storage medium

An image processing method performed by an image processing apparatus, the image processing method comprising:

• acquiring reference information which indicates at least one of a number of objects detected from a frame, a density of an object in a frame, or a frame rate;
• and
• tracking an identical object between frames, wherein
• in the tracking, each of objects for which a difference in a detection position between the frames is smaller than a threshold value corresponding to the reference information is determined to be an identical object, and each of objects for which a difference in the detection position between the frames is equal to or larger than the threshold value is not determined to be an identical object.

A non-transitory computer-readable storage medium in which a computer program is stored, the computer program causing a computer to:

• acquire reference information which indicates at least one of a number of objects detected from a frame, a density of an object in a frame, or a frame rate;
• and
• track an identical object between frames, wherein
• the tracking determines that each of objects for which a difference in a detection position between the frames is smaller than a threshold value corresponding to the reference information is an identical object, and does not determine that each of objects for which a difference in the detection position between the frames is equal to or larger than the threshold value is an identical object.
