  • Patent number: 10289924
    Abstract: A system and method are provided for the correction of a warped page image. The method first accepts a camera image of a page, creates a filtered edge map, and identifies text-likely regions. The filtered edge map and text-likely regions are projected into a polar coordinate system to determine page lines and warped image page curves. An adaptive two-dimensional (2D) ruled mesh piecewise planar approximation of a warped page surface is created. A three-dimensional (3D) model is created using the adaptive 2D ruled mesh and the estimate of the camera focal length estimate. Using the 3D model, a 2D target mesh is created for rectifying the image of the page. In one aspect, the adaptive 2D ruled mesh is projected onto a 3D warped page surface using the estimated camera focal length and an estimated surface normal of each planar strip from the adaptive 2D ruled mesh.

  • Patent number: 10210602
    Abstract: A system and method are provided for normalizing a camera focal length. A perspective geometry estimator accepts a scanned image from a camera having an undefined focal length, and generates a normalized focal length estimate for the image. The normalized focal length estimate is compared to a normalized focal length density distribution. If the normalized focal length estimate meets a minimum threshold of probability, the normalized focal length estimate is selected and the image is processed using the selected normalized focal length estimate. If the normalized focal length estimate fails to meet the minimum threshold of probability, the image is processed using the highest probability prior normalized focal length from the normalized focal length density distribution.

    Abstract: A hybrid CT dataset is obtained from a combination of an integrating detector and a photon-counting detector. The hybrid CT dataset contains sparse spectral energy data and dense energy integration data.

  • Patent number: 10121078
    Abstract: The present invention provides techniques for detecting foreign objects in a region of interest in maritime environments. Image data indicative of a sequence of successively acquired images of the region of interest, is analyzed to determine candidate points of interest, and data indicative of said points is processed to identify candidate points that are adjacently accumulated in different locations in images data. Grouping data may be then generated based on the identified accumulations of candidate points indicative of a group of said candidate points. The grouping data is processed to identify spatio-temporal correlation between the points in the group and determine a corresponding track function, thereby enabling detection of a presence of a foreign object in the image data.

  • Patent number: 10107769
    Abstract: A multimodality imaging system and method for mineralogy segmentation is disclosed. Image datasets of the sample are generated for one or more modalities, including x-ray and focused ion beam scanning electron microscope (FIB-SEM) modalities. Mineral maps are then created using Energy Dispersive X-ray spectroscopy (EDX) from at least part of the sample covered by the image datasets. The EDX mineral maps are applied as a mask to the image datasets to identify and label regions of minerals within the sample. Feature vectors are then extracted from the labeled regions via feature generators such as Gabor filters. Finally, machine learning training and classification algorithms such as Random Forest are applied to the extracted feature vectors to construct a segmented image representation of the sample that classifies the minerals within the sample.
