Abstract
An example apparatus for re-identifying objects includes an image receiver to receive a first image and a second image of an object with an identity. The apparatus also includes a fused model generator to fuse a global representation of the object with local representations of pose parts of the object to generate a fused representation of the object based on the first image. The apparatus further includes an object re-identifier to re-identify the object with the identity in the second image based on the fused representation.
Claims20
An apparatus for re-identifying objects in images, the apparatus comprising:
- at least one memory;
- instructions;
- and
- processor circuitry to execute the instructions to at least:
- receive a first image and a second image of an object with an identity;
- fuse a global representation of the object with local representations of pose parts of the object to generate a fused representation of the object based on the first image;
- and
- re-identify the object with the identity in the second image based on the fused representation.
A method for re-identifying objects in images, the method comprising:
- receiving, via a processor, a first input object image and a second input object image of an object with an identity;
- globally modeling, via the processor, the object based on the first input object image to generate a global representation, the global representation including a feature map;
- estimating, via the processor, pose keypoints of the object in the first input object image;
- generating a skeleton structure of the object based on the pose keypoints;
- modeling, via the processor, local parts of the object in the first input object image based on the feature map and the pose keypoints to generate local representations;
- fusing, via the processor, the global representation of the object with the local representations of pose parts of the object to generate a fused representation of the object based on the first input object image;
- and
- re-identifying, via the processor, the object with the identity in the second input object image based on the fused representation.
A system for re-identifying objects in images, the system comprising:
- means for receiving a first image and a second image of an object with an identity;
- means for fusing a global representation of the object with local representations of pose parts of the object to generate a fused representation of the object based on the first image;
- and
- means for re-identifying the object with the identity in the second image based on the fused representation.
