Abstract
Methods, apparatus, and articles of manufacture to detect shapes are disclosed. Example methods disclosed herein include determining a first likelihood of detection for a reference shape at a first distance from an image capturing device, and storing the reference shape in a first group of a plurality of groups in the database based on a comparison of the first likelihood of detection with a first threshold, the first group associated with the first distance. Disclosed examples also include selecting reference shapes of the first group to compare to an object outline detected in an image in response to a query, the query including a depth value associated with the detected object outline, the selecting of the reference shapes of the first group based on the depth value.
Claims20
An apparatus to manage a database for object recognition, the apparatus comprising:
- a detector to determine a first likelihood of detection for a reference shape at a first distance from an image capturing device;
- a grouper to store the reference shape in a first group of a plurality of groups in the database based on a comparison of the first likelihood of detection with a first threshold, the first group associated with the first distance;
- and
- a selector to select reference shapes of the first group to compare to an object outline detected in an image in response to a query, the query including a depth value associated with the detected object outline, the selector to select the reference shapes of the first group based on the depth value.
A tangible machine readable storage medium comprising instructions that, when executed, cause a processor to at least:
- determine a first likelihood of detection for a reference shape at a first distance from an image capturing device;
- store the reference shape in a first group of a plurality of groups in the database based on a comparison of the first likelihood of detection with a first threshold, the first group associated with the first distance;
- and
- select reference shapes of the first group to compare to an object outline detected in an image in response to a query, the query including a depth value associated with the detected object outline, the selecting of the reference shapes of the first group based on the depth value.
A method comprising:
- determining, by executing an instruction with a processor, a first likelihood of detection for a reference shape at a first distance from an image capturing device;
- storing the reference shape in a first group of a plurality of groups in the database based on a comparison of the first likelihood of detection with a first threshold, the first group associated with the first distance;
- and
- selecting, by executing an instruction with the processor, reference shapes of the first group to compare to an object outline detected in an image in response to a query, the query including a depth value associated with the detected object outline, the selecting of the reference shapes of the first group based on the depth value.
