Patent number: 11688061Abstract: Computer-implemented methods and systems are provided for interpreting a whole-slide image of a tissue specimen. Such a method includes detecting biological entities in a region of interest independently at each magnification level in a whole-slide image. An entity graph is generated for each magnification level, the entity graph comprising nodes, representing respective biological entities detected at that magnification level, interconnected by edges representing interactions between entities. The method also includes, for each region of interest, generating a hierarchical graph, defining a hierarchy of the entity graphs for that region, in which nodes of different entity graphs are interconnected by hierarchical edges representing hierarchical relations between nodes of the entity graphs.Type: GrantFiled: November 20, 2020Date of Patent: June 27, 2023Assignee: International Business Machines CorporationInventors: Pushpak Pati, Guillaume Jaume, Antonio Foncubierta Rodriguez, Maria Gabrani

Patent number: 11515009Abstract: Embodiments of the invention relate to a computer-implemented method for quantifying a biomarker in a tissue sample of an organism. An image analysis system receives images of a stained tissue sample. Each received digital image depicts the tissue sample region at the end of an exposure interval. The system analyzes the intensity values and exposure intervals of the received digital images for determining the time when the intensity values corresponding to the plurality of exposure intervals ordered according to ascending exposure interval lengths reach a plateau (saturation residence timeāSRT). The system determines the amount of a biomarker in the tissue sample and/or predicts a tumor stage and/or a treatment recommendation as a function of the SRT.Type: GrantFiled: March 19, 2018Date of Patent: November 29, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Govind Kaigala, Anna Fomitcheva Khartchenko, Aditya Kashyap, Maria Gabrani, Pushpak Pati

Patent number: 11501061Abstract: A system and process for extracting information from filled form images is described. In one example, the claimed invention first extracts textual information and the hierarchy in a blank form. This information is then used to extract and understand the content of filled forms. In this way, the system does not have to analyze from the beginning each filled form. The system is designed so that it remains as generic as possible. The number of hard-coded rules in the whole pipeline was minimized to offer an adaptive solution able to address the largest number of forms, with various structures and typography. The system is also created to be integrated as a built-in function in a larger pipeline. The form understanding pipeline could be the starting point of any advanced Natural Language Processing application.Type: GrantFiled: November 22, 2021Date of Patent: November 15, 2022Assignee: International Business Machines CorporationInventors: Antonio Foncubierta Rodriguez, Guillaume Jaume, Maria Gabrani

Patent number: 11062133Abstract: Computer-implemented methods are provided for generating a data structure representing tabular information in a scanned image. Such a method can include storing image data representing a scanned image of a table, processing the image data to identify positions of characters and lines in the image, and mapping locations in the image of information cells, each containing a set of the characters, in dependence on said positions. The method can also include, for each cell, determining cell attribute values, dependent on the cell locations, for a predefined set of cell attributes, and supplying the attribute values as inputs to a machine-learning model trained to pre-classify cells as header cells or data cells in dependence on cell attribute values.Type: GrantFiled: June 24, 2019Date of Patent: July 13, 2021Assignee: International Business Machines CorporationInventors: Antonio Foncubierta Rodriguez, Maria Gabrani, Waleed Farrukh

Patent number: 10706535Abstract: The invention relates to the automated determination of the staining quality of an IHC stained biological sample. A plurality of features is extracted from a digital IHC stained tissue image. The features are input into a first classifier configured to identify the extended tissue type of the depicted tissue as a function of the extracted features. An extended tissue type is a tissue type with a defined expression level of the tumor marker. In addition, the extracted features are input into a second classifier configured to identify a contrast level of the depicted tissue as a function of at least some second ones of the extracted features. The contrast level indicates the intensity contrast of pixels of the stained tissue. Then, a staining quality score of the image is computed as a function of the identified extended tissue type and the identified contrast level.Type: GrantFiled: September 8, 2017Date of Patent: July 7, 2020Assignee: International Business Machines CorporationInventors: Nuri Murat Arar, Maria Gabrani, Govind Kaigala, Aditya Kashyap, Anna Fomitcheva Khartchenko, Pushpak Pati

Patent number: 10685462Abstract: The invention relates to a computer-implemented method for automatically extracting data from a digital image comprising a graphical representation of quantitative data. The method comprises: Basic graphical objects are detected and structural primitives determined comprising grouping the basic graphical objects based on geometric relations. A semantic label is assigned to each of the structural primitives. A spatial data region of the graphical representation is determined using the semantic labels of the structural primitives. Quantitative data values are extracted which are represented by structural primitives within the data region which are assigned with first semantic labels identifying the respective structural primitives to represent quantitative data. The extracted quantitative data values are provided in units of pixels according to an image coordinate system.Type: GrantFiled: December 27, 2018Date of Patent: June 16, 2020Assignee: International Business Machines CorporationInventors: Konstantinos Bekas, Gabriel Cuendet, Maria Gabrani, Peter W.
