Image processing apparatus, image processing method, and non-transitory computer-readable storage medium to perform a tracking process, using a tracking model
An image processing apparatus comprises a tracking unit configured to perform a tracking process, using a tracking model, in which a tracking target in a captured image is tracked, and a switching unit configured to switch the tracking model to a first model that tracks a second object as the tracking target when masking of the first object by the second object is detected while the tracking unit tracks the first object as the tracking target, and to switch the tracking model to a second model that tracks the first object as the tracking target when termination of the masking is detected.
1. An image processing apparatus, comprising:
at least one processor; and
at least one memory having stored thereon instructions which, when executed by the at least one processor, cause the image processing apparatus at least to:
perform a tracking process, using a tracking model, in which a tracking target in a captured image is tracked; and
switch the tracking model to a first model that tracks a second object as the tracking target when masking of a first object by the second object is detected while the first object is tracked as the tracking target, and to switch the tracking model to a second model that tracks the first object as the tracking target when termination of the masking is detected,
wherein the masking of the first object by the second object is detected based on a first map representing a region of the first object in the captured image.
2. The image processing apparatus according to claim 1 , wherein
while the first object is tracked as the tracking target, when the masking of the first object by the second object is detected, the tracking model is switched to the first model constructed using an image of the second object, and when the termination of the masking is detected, the tracking model is switched to the second model constructed using an image of the first object.
3. The image processing apparatus according to claim 1 , wherein
when the masking is detected, the second object is determined as the tracking target based on a candidate of a region of the first object in the captured image and a second map representing a region of the second object in the captured image, and the tracking model is switched to the first model that tracks the determined second object as the tracking target.
4. The image processing apparatus according to claim 1 , wherein
the termination of the masking is detected based on a second map representing a region of the second object in the captured image.
5. The image processing apparatus according to claim 4 , wherein
when the termination of the masking is detected, the first object is determined as the tracking target based on a candidate of a region of the first object in the captured image and a first map representing a region of the first object in the captured image, and the tracking model is switched to the second model that tracks the determined first object as the tracking target.
6. The image processing apparatus according to claim 1 , wherein
when the masking is detected, whether to perform the switching is determined based on a candidate of a region of the first object in the captured image and a first map representing a region of the first object in the captured image.
7. The image processing apparatus according to claim 1 , wherein
the first model and the second model include a neural network and template matching.
8. The image processing apparatus according to claim 1 , further comprising
an image capturing device configured to capture the captured image.
9. An image processing method, comprising:
performing a tracking process, using a tracking model, in which a tracking target in a captured image is tracked; and
switching the tracking model to a first model that tracks a second object as the tracking target when masking of a first object by the second object is detected while the first object is tracked in the tracking as the tracking target, and switching the tracking model to a second model that tracks the first object as the tracking target when termination of the masking is detected,
wherein the masking of the first object by the second object is detected based on a first map representing a region of the first object in the captured image.
10. A non-transitory computer-readable storage medium that stores a computer program for causing a computer having at least one processor, when executing the computer program to:
perform a tracking process, using a tracking model, in which a tracking target in a captured image is tracked; and
switch the tracking model to a first model that tracks a second object as the tracking target when masking of a first object by the second object is detected while the first object is tracked as the tracking target, and to switch the tracking model to a second model that tracks the first object as the tracking target when termination of the masking is detected,
wherein the masking of the first object by the second object is detected based on a first map representing a region of the first object in the captured image.
