OBJECT DETECTION METHOD, OBJECT DETECTION APPARATUS, AND PROGRAM
First Claim
1. An object detection method comprising:
- an acquisition step of acquiring an image;
a generation step of generating a plurality of layer images by enlarging or reducing the image;
a detection step of detecting a first object <
head portion surrounding region>
from at least one of the plurality of layer images;
an estimation step of estimating a specific object <
head portion region>
based on the detected first object;
a selection step of selecting at least one of the plurality of layer images based on the estimated specific object;
a detection step of detecting a second object <
entire body of a person>
larger than the detected first object in the selected layer image;
a estimation step of estimating the specific object based on the detected second object; and
a determination step of determining the specific object based on the specific object estimated based on the first object and the specific object estimated based the second object.

Abstract
An object detection method includes an image acquisition step of acquiring an image including a target object, a layer image generation step of generating a plurality of layer images by one or both of enlarging and reducing the image at a plurality of different scales, a first detection step of detecting a region of at least a part of the target object as a first detected region from each of the layer images, a selection step of selecting at least one of the layer images based on the detected first detected region and learning data learned in advance, a second detection step of detecting a region of at least a part of the target object in the selected layer image as a second detected region, and an integration step of integrating a detection result detected in the first detection step and a detection result detected in the second detection step.

11. An object detection apparatus comprising:
-
an acquisition unit configured to acquire an image; a generation unit configured to generate a plurality of layer images by enlarging or reducing the image; a first detection unit configured to detect a first object from at least one of the plurality of layer images; a first estimation unit configured to estimate a specific object based on the detected first object; a layer image selection unit configured to select at least one of the plurality of layer images based on a size of the estimated specific object; a second detection unit configured to detect a second object larger than the first object in the selected layer image; a second estimation unit configured to estimate the specific object based on the detected second object; and a determination unit configured to determine the specific object based on the specific object estimated by the first estimation unit and the specific object estimated by the second estimation unit.
