Abstract
A method of identifying, with a camera, an object in an image of a scene, by determining the distinctiveness of each of a number of attributes of an object of interest, independent of the camera viewpoint, determining the detectability of each of the attributes based on the relative orientation of a candidate object in the image of the scene, determining a camera setting for viewing the candidate object based on the distinctiveness of an attribute, so as to increase the detectability of the attribute, and capturing an image of the candidate object with the camera setting to determine the confidence that the candidate object is the object of interest.
Claims11
A method of identifying, with a camera, an object in an image of a scene, the method comprising the steps of:
- determining a distinctiveness of each of a plurality of attributes of an object of interest, independent of a camera viewpoint, the distinctiveness describing a uniqueness of the attribute;
- determining a detectability of each of the plurality of attributes of a candidate object in the image of the scene based on a relative orientation of the candidate object, the detectability describing a degree of certainty with which the attribute can be detected in an image of the candidate object;
- determining a camera setting for viewing the candidate object based on the determined distinctiveness of at least one attribute, so as to increase the detectability of the at least one attribute;
- and
- capturing an image of the candidate object with the determined camera setting to determine a confidence that the candidate object is the object of interest.
An apparatus comprising:
- a camera for capturing an image of an object of interest and an image of a candidate object in a scene;
- a processor;
- and
- a memory storing a computer executable software program for directing the processor to perform a method for identifying, with the camera, an object in the image of the scene, the method comprising the steps of:
- determining a distinctiveness of each of a plurality of attributes of the object of interest, independent of a camera viewpoint, the distinctiveness describing a uniqueness of the object;
- determining a detectability of each of the plurality of attributes of a candidate object in the image of the scene based on a relative orientation of the candidate object, the detectability describing a degree of certainty with which the attribute can be detected in an image of the candidate object;
- determining a camera setting for viewing the candidate object based on the determined distinctiveness of at least one attribute, so as to increase the detectability of the at least one attribute;
- and
- capturing an image of the candidate object with the determined camera setting to determine a confidence that the candidate object is the object of interest.
A computer readable non-transitory memory storing a computer executable software program for directing processor to perform a method for identifying, with a camera, an object in an image of a scene, the method comprising the steps of:
- determining a distinctiveness of each of a plurality of attributes of the object of interest, independent of a camera viewpoint, the distinctiveness describing a uniqueness of the attribute;
- determining a detectability of each of the plurality of attributes of a candidate object in the image of the scene based on a relative orientation of the candidate object;
- determining a camera setting for viewing the candidate object based on the determined distinctiveness of at least one attribute, so as to increase the detectability of the at least one attribute, the detectability describing a degree of certainty with which the attribute can be detected in an image of a candidate object;
- and
- capturing an image of the candidate object with the determined camera setting to determine a confidence that the candidate object is the object of interest.
