Abstract: In general, in one aspect, a method includes receiving, by one or more processors, a query image, obtaining, by the one or more processors, search results responsive to the query image, each search result identifying a corresponding web page containing an image that is determined to be responsive to the query image, the search results being ordered in a first arrangement, obtaining, by the one or more processors, text labels associated with the query image, and generating, by the one or more processors a second arrangement of the search results by ordering the search results based on a presence in the respective corresponding web pages of one or more of the text labels associated with the query image. This and other implementations of this aspect can include corresponding systems, apparatus, and computer program products.

Abstract: In general, in one aspect, a method includes receiving a query image, obtaining a set of text labels associated with the query image, each text label associated with a confidence score that the text label accurately describes a topic of the query image, selecting a first text label associated with the query image, the first text label having a highest confidence score among the set of text labels, selecting a subset of the set of text labels that have a confidence score greater than a confidence score threshold, obtaining search results responsive to the query image, and in response to at least one of the search results identifying a web page containing the first text label, sending data that causes a client device to display the subset of text labels with the search results.

Abstract: A method and system for visualizing regions in an image is provided. The method comprises computing a regional response around a region in the image, deriving a region score based on from the regional response for the region and labeling the region in the image by comparing the region score to a plurality of probabilistic models.

Abstract: The present invention relates to riminophenazines having heteroaromatic substitutions, including those with 2-heteroaryl-amino substituents, to their preparation, and to their use as drugs for treating Mycobacterium tuberculosis and other microbial infections, either alone or in combination with other anti-infective treatments. A general representation of the 2-(heteroaryl)amino-riminophenazines is shown below.

Abstract: Methods, systems, and apparatus, include computer programs encoded on a computer-readable storage medium, for determining keywords for an image that supports an overlay content item. A method includes identifying, using one or more processors, an image that is to support an overlay content item, the image being presented on a web site and including a portion that is designated as being enabled to receive and display the overlay content item; evaluating pixel data associated with the image including determining one or more labels that are associated with content included within the image; and determining one or more keywords for the image based at least in part on the one or more labels.

Abstract: Methods, systems, and apparatus, including computer program products, for ranking images are disclosed. An image search subsystem generates an adjustment factor representative of a quality measure of an image relative to a search query. The quality represents a relevance of the image to the query. The adjustment factor can be computed based on relevance data for the image to the query and image similarity data representing a relative similarity between the image and other images relevant to the query. The relevance data can be based on user actions in response to the image being included in search results for the query. The adjustment factor can be scaled based on whether the relevance data and the image similarity data both indicate that the image is relevant to the search query. A relevance score is computed based on the adjustment factor (e.g., a product of the adjustment factor and relevance score).

Abstract: Methods, systems and apparatus for identifying result images for a query image. One or more labels that are associated with the query image are obtained. Candidate images matching the query labels are identified. Visual similarity scores are generated for the candidate images. Each visual similarity score represents the visual similarity of a respective candidate image to the query image. Relevance scores are generated for each of the candidate images based on the visual similarity scores. Each relevance score represents a measure of relevance of the respective candidate images to the query image. The candidate images are ranked based on the relevance scores, a highest ranking subset of the candidate images being identified as result images and referenced by image search results. The result images can be candidate images that satisfy a similarity condition relative to the query image and other result images.
