Abstract
A tracking device includes a processor including hardware. The processor is configured to: set a start frame and an end frame in a video including multiple frames; perform forward tracking in frames subsequent to the start frame based on a region of a tracking target in the start frame; perform backward tracking in frames previous to the end frame based on a region of the tracking target in the end frame; and generate a combined mask image by combining a forward mask image based on the forward tracking with a backward mask image based on the backward tracking.
Claims11
A tracking device comprising:
- a processor including hardware,
- the processor being configured to:
- set a start frame and an end frame in a video including multiple frames;
- perform forward tracking of tracking a tracking target in a forward direction in frames subsequent to the start frame based on a region of the tracking target in the start frame;
- perform backward tracking of tracking the tracking target in a backward direction in frames previous to the end frame based on a region of the tracking target in the end frame;
- and
- generate a combined mask image indicating a region of the tracking target in each of the frames in which the forward tracking and the backward tracking have been performed by combining a forward mask image based on the forward tracking with a backward mask image based on the backward tracking.
An endoscope system comprising:
- a memory storing a trained model;
- an endoscopic scope configured to capture a detection image;
- and
- a processor configured to receive the detection image as input and detect a position of a given subject in the detection image using the trained model, wherein
- the trained model is trained by machine learning based on training data in which a combined mask image is associated with an image of each of multiple frames included in a video, the combined mask image being generated by:
- setting a start frame and an end frame in the video including the multiple frames;
- performing forward tracking of tracking a tracking target in a forward direction in frames subsequent to the start frame based on a region of the tracking target in the start frame;
- performing backward tracking of tracking the tracking target in a backward direction in frames previous to the end frame based on a region of the tracking target in the end frame;
- and
- generating the combined mask image indicating a region of the tracking target in each of the frames in which the forward tracking and the backward tracking have been performed by combining a forward mask image based on the forward tracking with a backward mask image based on the backward tracking.
A tracking method comprising:
- setting a start frame and an end frame in a video including multiple frames;
- performing forward tracking of tracking a tracking target in a forward direction in frames subsequent to the start frame based on a region of the tracking target in the start frame;
- performing backward tracking of tracking the tracking target in a backward direction in frames previous to the end frame based on a region of the tracking target in the end frame;
- and
- generating a combined mask image indicating a region of the tracking target in each of the frames in which the forward tracking and the backward tracking have been performed by combining a forward mask image based on the forward tracking with a backward mask image based on the backward tracking.
