  • Publication number: 20220245821
    Abstract: A system is proposed for automated detection and segmentation of lung cancer from registered pairs of thoracic Computerized Tomography (CT) and Positron Emission Tomography (PET) scans. The system segments the lungs from the CT data and uses this as a volumetric constraint that is applied on the PET data set. Cancer candidates are segmented from the PET data set from within the image regions identified as lungs. Weak signal candidates are rejected. Strong signal candidates are back projected into the CT set and reconstructed to correct for segmentation errors due to the poor resolution of the PET data. Reconstructed candidates are classified as cancer or not using a Convolutional Neural Network (CNN) algorithm. Those retained are 3D segments that are then attributed and reported. Attributes include size, shape, location, density, sparseness and proximity to any other pre-identified anatomical feature.

  • Publication number: 20210319878
    Abstract: A system and method, after performing the comparison, identifies at least one a match of the target feature from the imaging source with a library of target features. The system and method receive at least one numerical representation from a diagnostic source of a target feature. The system and method compares the at least one numerical representation of the target feature with a library of numerical representations. The system and method, after performing the comparison, identifies at least one match of the target feature from the imaging source with the library.

  • Patent number: 10691942
    Abstract: A system and methods for unsupervised land use and land cover detection using a classifier that produces a plurality of class image layers which are filtered to remove misclassified same-label pixel groupings, a class resolution module that reduces multiple pixel labels to a single one if applicable and a reconstruction module that generates the output land use and land cover image.

  • Patent number: 10679055
    Abstract: A system and methods for radiometric anomaly detection using non-target clustering, wherein a hierarchy generator organizes the image information content into a hierarchical data representation structure, and a non-target clustering engine processes the hierarchical model to identify large homogeneous regions and significantly dissimilar smaller regions within them based on search criteria.

  • Patent number: 10515272
    Abstract: A system and methods for muddy water detection using normalized semantic layers, wherein a spectrum analyzer isolates spectrum bands within an image to produce a set of three normalized differential index images from which a composite color image is created, from which a power band is computed, from which a two-color image is produced, and then filters image components within the two-color representation based on defined criteria.

  • Patent number: 10372984
    Abstract: A system and various methods for processing an image to produce a hierarchical image representation model, segment the image model using shape criteria to produce positive and negative training data sets as well as a search-space data set comprising shapes matched to a search query provided as input, and using the training data sets to train a machine learning model to improve recognition of shapes that are similar to an input query without being exact matches, to improve object recognition.

  • Patent number: 9619711
    Abstract: Automatic characterization or categorization of portions of an input multispectral image based on a selected reference multispectral image. Sets (e.g., vectors) of radiometric descriptors of pixels of each component of a hierarchical representation of the input multispectral image can be collectively manipulated to obtain a set of radiometric descriptors for the component. Each component can be labeled as a (e.g., relatively) positive or negative instance of at least one reference multispectral image (e.g., mining materials, crops, etc.) through a comparison of the set of radiometric descriptors of the component and a set of radiometric descriptors for the reference multispectral image. Pixels may be labeled (e.g., via color, pattern, etc.) as positive or negative instances of the land use or type of the reference multispectral image in a resultant image based on components within which the pixels are found.

  • Patent number: 9031325
    Abstract: A system for automatically extracting or isolating structures or areas of interest (e.g., built-up structures such as buildings, houses, shelters, tents; agricultural areas; etc.) from HR/VHR overhead imagery data by way of making as little as a single pass through a hierarchical data structure of input image components (where pixels are grouped into components based on any appropriate definition or measure of dissimilarity between adjacent pixels of the input image) to identify candidate components (e.g., possible structures of interest) free of necessarily having to re-iterate the same operator configured with different threshold parameters for a plurality of values.
