Abstract
An object locating method comprises deciding, for at least one frame of a video stream and based on at least one parameter representative of a change between a scene represented by the at least one frame and a scene represented by a reference frame of the video stream, whether determination of a location of at least one object (11, 13, 15, 17, 19) in the at least one frame is based on object detection applied to the at least one frame, or is based on a transformation of a location of the at least one object (11, 13, 15, 17, 19) detected in the reference frame.
Claims21
1-32. (canceled)
An object locator comprising:
- processing circuitry;
- and
- memory comprising instructions executable by the processing circuitry whereby the object locator is operative to:
- decide, for at least one frame of a video stream and based on at least one parameter representative of a change between a scene represented by the at least one frame and a scene represented by a reference frame of the video stream, whether determination of a location of at least one object in the at least one frame is based on object detection applied to the at least one frame, or is based on a transformation of a location of the at least one object detected in the reference frame.
A user device comprising:
- a camera configured to record video and generate a video stream;
- an object locator, the object locator comprising processing circuitry and memory comprising instructions executable by the processing circuitry whereby the object locator is operative to:
- decide, for at least one frame of a video stream and based on at least one parameter representative of a change between a scene represented by the at least one frame and a scene represented by a reference frame of the video stream, whether determination of a location of at least one object in the at least one frame is based on object detection applied to the at least one frame, or is based on a transformation of a location of the at least one object detected in the reference frame.
An object locating method, comprising:
- deciding, for at least one frame of a video stream and based on at least one parameter representative of a change between a scene represented by the at least one frame and a scene represented by a reference frame of the video stream, whether determination of a location of at least one object in the at least one frame is based on object detection applied to the at least one frame, or is based on a transformation of a location of the at least one object detected in the reference frame.
A non-transitory computer readable recording medium storing a computer program product for controlling an object locator, the computer program product comprising program instructions which, when run on processing circuitry the object locator, causes the object locator to:
- decide, for at least one frame of a video stream and based on at least one parameter representative of a change between a scene represented by the at least one frame and a scene represented by a reference frame of the video stream, whether determination of the location of the at least one object in the at least one frame is based on the object detection applied to the at least one frame, or is based on the transformation of the location of the at least one objected detected in the reference frame.
