Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for jointly performing text detection and layout analysis. In one aspect, a method comprises processing the image and a set of object queries to generate an encoded representation of the image and an encoded representation of the set of object queries; processing the encoded representation of the image and the encoded representation of the set of object queries to generate a set of text detection masks; processing the encoded representation of the set of object queries to generate layout relevance measures; processing the encoded representation of the set of object queries to generate textness scores for the text detection masks; generating a text detection output that defines respective areas of the image that include text items; and generating a layout analysis output that defines clusters of respective areas of the image identified by the text detection masks.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting text instances of arbitrary shapes, sizes, and locations. In one aspect, a method comprises processing an image depicting one or more text instances, generating a respective prediction for each character in a sequence of characters that are predicted to be depicted in the text instance, the respective prediction comprising a respective character class to which the predicted character belongs, the respective character class selected from a set that includes printable character classes and a space character class and a bounding box that contains the character within the image, and grouping the sequence of characters into a plurality of words based on locations of characters that are predicted to belong to the space character class.
