Image ranking based on attribute correlation

摘要

Images are retrieved and ranked according to relevance to attributes of a multi-attribute query through training image attribute detectors for different attributes annotated in a training dataset. Pair-wise correlations are learned between pairs of the annotated attributes from the training dataset of images. Image datasets may are searched via the trained attribute detectors for images comprising attributes in a multi-attribute query. The retrieved images are ranked as a function of comprising attributes that are not within the query subset plurality of attributes but are paired to one of the query subset plurality of attributes by the pair-wise correlations, wherein the ranking is an order of likelihood that the different ones of the attributes will appear in an image with the paired one of the query subset plurality of attributes.

1. A method for retrieving and ranking multi-attribute query results according to relevance to attributes of a multi-attribute query, the method comprising:
training each of a plurality of image attribute detectors for one each of a plurality of different attributes that are annotated in a training dataset of images of people; learning via a processor a plurality of pair-wise correlations between each pair of the plurality of annotated attributes from the training dataset of images; searching via the trained attribute detectors an input image dataset for images comprising at least one of a multi-attribute query subset plurality of the annotated attributes; retrieving a plurality of images from the searching of the input image dataset that each comprise at least one of the query subset plurality of attributes; and ranking the retrieved plurality of images as a function of comprising different ones of the attributes that are not within the query subset plurality of attributes but are paired to the at least one of the query subset plurality of attributes by the pair-wise correlations, wherein the ranking is an order of likelihood that the different ones of the attributes will appear in an image with the paired at least one of the query subset plurality of attributes.
