Abstract: A computer-implemented method for detecting a target object on a document page that includes detecting a sample target area on a sample document page, generating an image by overlapping a plurality of sample document pages with one another, and detecting one or more cells within the sample target area on the image. The sample target area includes a sample target object. The method further includes extracting one or more informational features from each of the one or more cells. The one or more informational features define characteristics of a corresponding cell of the one or more cells. A machine learning model is trained using the one or more informational features extracted from each of the one or more cells, to detect the sample target object. A target object on a document page is detected using the trained machine learning model.

Abstract: Systems and methods are disclosed for displaying 2D building drawings in a 3D space. One method comprises receiving 2D building drawings from a device, the 2D building drawings include symbols and/or metadata, and the symbols indicate a correlation between an elevation, a floorplan, and a section of the 2D building drawings. The plurality of 2D building drawings is processed to detect the correlation between the symbols and the metadata. A selection is received of a first 2D building drawing from the 2D building drawings and/or a first symbol in the first 2D building drawing. A second 2D building drawing is retrieved from the 2D building drawings based on the correlation between the first symbol and a second symbol of the second 2D building drawing. A 3D design model is generated by aligning the first 2D building drawing and the second 2D building drawing in the 3D space.

Abstract: Systems and methods are disclosed for automatically aligning drawings. One method comprises receiving a source drawing and a target drawing, determining main axes of the source and target drawings respectively, and aligning the main axis of the source drawing to the main axis of the target drawing. A plurality of source feature point vectors and target feature point vectors may be generated from the source and target drawings, whose main axes have been aligned. A predetermined number of matching FPV pairs may then be determined across the source and target drawings, and the source drawing may be aligned with the target drawings based on the matching FPV pairs.

Abstract: A method of visually interacting with an electronically stored document having a plurality of visual objects. The method includes accessing the document that includes a closed region characterized by an open area boundary surrounding an open area. The method further includes displaying the document on a display. The method further includes receiving a user input of a region of interest within the document and in the open area. The method further includes iteratively, in a time interval of multiple segments, dynamically displaying a fill area in each of the multiple time segments. The fill area is defined by outwardly expanding vertices from the region of interest and bounded by an expanding fill perimeter limited by the open area boundary. The fill area is coextensive with the open area upon the fill perimeter coinciding with the open area boundary.

Abstract: A method of computerized presentation of a document set view for auditing information of a set of documents. The method includes the initial step of receiving on a computer a selection of an original document. The original document has multiple pages with each of the pages of the original document having corresponding page content. A selection is received from the user of a first region a page of the original document. This process is repeated to retrieve a text string from all of the pages. An addendum document with multiple pages is received. A text string is retrieved from the pages of the addendum document without user intervention. A document set view is provided using the retrieved text stings and displayed for the user to update the associated information and thus allowing for the user to perform a data audit of the automated portion of the process.
