Abstract:
1. A method comprising: under control of one or more processors specifically configured with executable instructions, receiving, at a search engine, a query associated with a query image, the query image including a plurality of pixels; categorizing a first portion of the plurality of pixels as foreground pixels; categorizing a second portion of the plurality of pixels as background pixels; determining saliency scores for each of the plurality of pixels based on the foreground pixels and the background pixels, the saliency scores comprising contrast-based saliency scores; normalizing the saliency scores to create normalized saliency scores; transforming the normalized saliency scores to create a prior probability distribution; determining a search intent based on the prior probability distribution using a dual-sigmoid approximation; and identifying, from a set of images, one or more images that match the query image based on the search intent.
