Abstract
An information processing apparatus is configured to acquire detection target sizes at individual positions in an image, set a plurality of detection regions for the image, and detect a detection target in each detection region from the image acquired. At the time of setting the detection regions, based on the detection target sizes at the individual positions, sizes of the detection regions at the individual positions in the image and overlapping ranges between adjacent detection regions are set.
Claims20
An information processing apparatus comprising:
- an image acquisition unit configured to acquire an image;
- a size acquisition unit configured to acquire detection target sizes at individual positions in the image;
- a region setting unit configured to set a plurality of detection regions for the image;
- and
- a detection unit configured to detect, from the image acquired by the image acquisition unit, a detection target in each of the detection regions, wherein the region setting unit is configured to set, based on the detection target sizes at the individual positions acquired by the size acquisition unit, sizes of the detection regions at the individual positions in the image and overlapping ranges between adjacent detection regions.
An information processing method comprising:
- an image acquisition step of acquiring an image;
- a size acquisition step of acquiring detection target sizes at individual positions in the image;
- a region setting step of setting a plurality of detection regions for the image;
- and
- a detection step of detecting, from the image acquired by the image acquisition step, a detection target in each of the detection regions, wherein
- the region setting step sets, based on the detection target sizes at the individual positions acquired by the size acquisition step, sizes of the detection regions at the individual positions in the image and overlapping ranges between adjacent detection regions.
A storage medium storing a program for causing a computer to function as an information processing apparatus comprising:
- an image acquisition unit configured to acquire an image;
- a size acquisition unit configured to acquire detection target sizes at individual positions in the image;
- a region setting unit configured to set a plurality of detection regions for the image;
- and
- a detection unit configured to detect, from the image acquired by the image acquisition unit, a detection target in each of the detection regions, wherein
- the region setting unit is configured to set, based on the detection target sizes at the individual positions acquired by the size acquisition unit, sizes of the detection regions at the individual positions in the image and overlapping ranges between adjacent detection regions.
