Object detection via validation with visual search

摘要

One exemplary embodiment involves receiving, at a computing device comprising a processor, a test image having a candidate object and a set of object images detected to depict a similar object as the test image. The embodiment involves localizing the object depicted in each one of the object images based on the candidate object in the test image to determine a location of the object in each respective object image and then generating a validation score for the candidate object in the test image based at least in part on the determined location of the object in the respective object image and known location of the object in the same respective object image. The embodiment also involves computing a final detection score for the candidate object based on the validation score that indicates a confidence level that the object in the test image is located as indicated by the candidate object.

主权项

1. A method comprising:
identifying a candidate region of a test image as potentially depicting an instance of an object; identifying a first region in an object image that is similar to the candidate region of the test image, the object image being different from the test image; performing a comparison of the first region with a second region of the object image, the second region known to actually depict the instance of the object; and determining a validation score for the candidate region based on the comparison, wherein identifying the candidate region, identifying the first region, performing the comparison, and determining the validation score are performed by a processor of a computer device executing instructions.
