Detection method and detection device
First Claim
1. A computer-implemented detection method comprising:
- in response to inputting a first image to a learned model, identifying a first estimated image from the input first image by using the learned model, the first image being an image including a region of a plurality of target objects, the first estimated image being an estimated image corresponding to entirety of a first target object being one of the plurality of target objects, the learned model being a model generated by learning training data including a partial image indicating a part of an object and a corresponding entire image indicating entirety of the object;
detecting a first region of the first target object in the first image in accordance with a comparison between the identified first estimated image and the first image, the first region being a region including a contour of entirety of the first target object;
identifying, based on a second image obtained by invalidating the first region from among the first image, a second estimated image with respect to a second target object by using the learned model, the second estimated image being an estimated image corresponding to entirety of the second target object, the second target object being one of the plurality of target objects other than the first target object; and
detecting a second region of the second target object in accordance with a comparison between the identified second estimated image and the second image, the second region being a region including a contour of entirety of the second target object, the comparison between the identified second estimated image and the second image being configured to exclude a region corresponding to the invalidated first region from the comparison between the identified second estimated image and the second image.

Abstract
A computer-implemented detection method includes, in response to inputting a first image including a region of one or more objects to a learned model, identifying a first entire image corresponding to entirety of a first object as a detection candidate, the learned model being generated by learning training data including an image corresponding to a part of an object and an entire image corresponding to entirety of the object, detecting an existing region of the first target object in the first image in accordance with a comparison between the identified first entire image and the region of the one or more target objects, and determining, based on a specific image obtained by invalidating the existing region in the first image, whether another target object is included in the first image.
