Image recognition device, method for image recognition device, and recording medium

Abstract

It is necessary to input and register the size of an object in advance for each installation environment, which takes time and effort. This image recognition device comprises: an image acquisition unit (11) that acquires an image; a detection unit (12) that detects a detection object from the image; an index creation unit (14) that creates an index for determining whether the detection object is a target object from the history of the location and size of the detection object; and a determination unit (15) that uses the index to determine whether the detection object is the target object, wherein the index is information representing a distribution trend of the location and size of the detection object in the history.

Dependencies are inferred from the claim text.
