Abstract
Systems, methods, and non-transitory computer-readable media can train a model to predict motion vectors for entities in video frames. A set of frames that correspond to a first video can be obtained. The set of frames can be provided as input to the model. A set of motion vectors for the set of frames can be obtained from the model, wherein each motion vector describes a trajectory of at least one entity in the set of frames.
Claims20
A computer-implemented method comprising:
- training, by a computing system, a model to predict motion vectors for entities in video frames;
- obtaining, by the computing system, a set of frames that correspond to a first video;
- providing, by the computing system, the set of frames as input to the model;
- and
- obtaining, by the computing system, a set of motion vectors for the set of frames from the model, wherein each motion vector describes a trajectory of at least one entity in the set of frames.
A system comprising:
- at least one processor;
- and
- a memory storing instructions that, when executed by the at least one processor, cause the system to perform:
- training a model to predict motion vectors for entities in video frames;
- obtaining a set of frames that correspond to a first video;
- providing the set of frames as input to the model;
- and
- obtaining a set of motion vectors for the set of frames from the model, wherein each motion vector describes a trajectory of at least one entity in the set of frames.
A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the computing system to perform a method comprising:
- training a model to predict motion vectors for entities in video frames;
- obtaining a set of frames that correspond to a first video;
- providing the set of frames as input to the model;
- and
- obtaining a set of motion vectors for the set of frames from the model, wherein each motion vector describes a trajectory of at least one entity in the set of frames.
