Abstract

The technology is directed to determining a class associated with an image. In some examples, a method determines the class associated with an image. The method can include determining a segmentation score for an image segment based on a comparison of the image segment and a region of an image. The region of the image can be associated with the image segment. The method further includes determining a confidence score for the image segment based on the segmentation score and a classification score. The classification score can be indicative of a similarity between the image segment and at least one class. The method further includes determining a class associated with the image based on the confidence score. The method further includes outputting the class associated with the image.

Dependent claims

A method for determining a class associated with an image, the method comprising:

determining a segmentation score for an image segment based on a comparison of the image segment and a region of an image, the region of the image associated with the image segment;
determining a confidence score for the image segment based on the segmentation score and a classification score, the classification score indicative of a similarity between the image segment and at least one class;
determining a class associated with the image based on the confidence score;
outputting the class associated with the image;
determining a second segmentation score for a second image segment based on a comparison of the second image segment and a second region of the image, the second region of the image associated with the second image segment;
and
determining a second confidence score for the second image segment based on the second segmentation score and a second classification score, the second classification score indicative of a similarity between the second image segment and at least one class.
