Abstract
In a case in which the size of a moving body changes by a position of the moving body, in order to accurately track the moving body without an effort of the user regardless of a change in the size, the present disclosure estimates a size of the moving body in each of the images of the frames, updates template data based on the estimated size of the moving body, and compares a candidate region that is a candidate of a region where the moving body is present in each of the images of the frames with the template data, and determines whether or not the moving body is positioned in the candidate region based on the comparison result.
Claims19
A moving body tracking method of tracking a position of a moving body in each of images of a plurality of frames configuring a sports image obtained by capturing a game of a sports, by a processor, the method comprising:
- estimating a size of the moving body in each of the images of the frames;
- updating template feature amount to a feature amount generated from a template image corresponding to the estimated size of the moving body, based on the estimated size of the moving body;
- and
- comparing a feature amount of a candidate region that is a candidate of a region where the moving body is present in each of the images of the frames with the template feature amount corresponding to the estimated size of the moving body, and determining whether or not the moving body is positioned in the candidate region based on the comparison result.
A moving body tracking device for tracking a position of a moving body in each of images of a plurality of frames configuring a sports image obtained by capturing a game of a sports,
- wherein a size of the moving body in each of the images of the frames is estimated;
- template feature amount to a feature amount generated from a template image corresponding to the estimated size of the moving body, based on the estimated size of the moving body is updated;
- and
- a feature amount of a candidate region that is a candidate of a region where the moving body is present in each of the images of the frames is compared with the template feature amount corresponding to the estimated size of the moving body, and it is determined whether or not the moving body is positioned in the candidate region based on the comparison result.
A storage medium that stores program which causes a processor to sequentially execute a process of tracking a position of a moving body in each of images of a plurality of frames configuring a sports image obtained by capturing a game of a sports, the process comprising:
- estimating a size of the moving body in each of the images of the frames;
- updating template feature amount to a feature amount generated from a template image corresponding to the estimated size of the moving body, based on the estimated size of the moving body;
- and
- comparing a feature amount of a candidate region that is a candidate of a region where the moving body is present in each of the images of the frames with the template feature amount corresponding to the estimated size of the moving body, and determining whether or not the moving body is positioned in the candidate region based on the comparison result.
