  • Patent number: 10860683
    Abstract: The general problem of pattern change discovery between high-dimensional data sets is addressed by considering the notion of the principal angles between the subspaces is introduced to measure the subspace difference between two high-dimensional data sets. Current methods either mainly focus on magnitude change detection of low-dimensional data sets or are under supervised frameworks. Principal angles bear a property to isolate subspace change from the magnitude change. To address the challenge of directly computing the principal angles, matrix factorization is used to serve as a statistical framework and develop the principle of the dominant subspace mapping to transfer the principal angle based detection to a matrix factorization problem. Matrix factorization can be naturally embedded into the likelihood ratio test based on the linear models. The method may be unsupervised and addresses the statistical significance of the pattern changes between high-dimensional data sets.

  • Patent number: 10613228
    Abstract: The technology described herein is a depth camera that uses structured light and modulated light to produce a depth image. The modulated and structured light allows a time-of-flight depth to be calculated for each unit (e.g., a single dot) of the reflected structured light image captured by the depth camera's image sensor. The time-of-flight depth can be used to accurately identify each unit of the reflected structured light image. Once each unit of the reflected structured light image is identified, a structured light triangulation algorithm can be used to calculate a depth for each unit of the reflected structured light image. The present technology also allows a confidence score to be generated for the assigned depths within the depth image by comparing the structured light depth for each unit to the TOF depth for each unit.

The image data extraction method includes converting RGB values of each pixel in the color image data into HSV values, performing threshold processing to binarize at least one of the converted S and V values of each pixel so that it will be converted into HS?V? values, generating composite image data including an X value, a Y value, and a Z value for each pixel, the X value, the Y value, and the Z value being obtained by adding values according to predetermined one-to-one combinations between any one of an R value, a G value, and a B value and any one of an H value, an S? value, and a V? value, and extracting the image area using the composite image data.

  • Patent number: 10339427
    Abstract: A principal-subordinate relationship between two subjects is decided with regard to multiple subjects included in an image. Similarly, with regard also to other images, a principal-subordinate relationship between two subjects is decided with regard to multiple subjects included in each image. In a case where a relationship exists in which a first subject is a subordinate subject and a second subject is principal subject, the system calculates a principal-subordinate relationship value that is higher than in a case where a relationship in which a first subject is a subordinate subject and a second subject is principal subject does not exist. The greater the number of subjects to which the first subject is subordinate from among the multiple subjects, the lower the principal-subordinate relationship value calculated. On the basis of the calculated principal-subordinate relationship values, a subject evaluation value is calculated for every subject.

  • Patent number: 10303302
    Abstract: A presentation system capable of detecting one or more gestures and contacts on a touch sensitive display. The presentation system can displaying indicia of such contacts, such as when a user writes with a fingertip, and can remove or alter such indicia responsive to other gestures and contacts. The system can accurately distinguish between types of gestures detected, such as between a writing gesture and an erasing gesture, on both large and small touch sensitive displays, thereby obviating the need for a user to make additional selective inputs to transition from one type of gesture to another. The presentation system can distinguish between gestures appropriate for one type of marking and another. The system can distinguish between contacts intended by the user as part of an erasure gesture, and those which are incidentally or accidentally made while the user is writing, drawing or annotating on a display surface.

  • Patent number: 10282447
    Abstract: A method, system and computer program product for processing hierarchical data is provided. A method for processing hierarchical data in a relational database includes receiving an input parameter in an initial query for querying an array in a hierarchical data object stored in a table of a relational database, and transforming the initial query into a transformed query configured to place all elements of the array into a different table and to apply a sub-query against the table for the input parameter. Once transformed, predicate evaluation logic of a relational engine of the relational database is applied to the transformed query that is then mapped to the initial query. Finally, responsive to receiving a subsequent instance of the initial query, the mapping is referred to in order to replace the initial query with the transformed query and to subsequently apply the predicate evaluation logic to the transformed query.

  • Patent number: 10229313
    Abstract: A system configured for tracking a human hand, e.g., in an interactive space, may comprise a distancing device, one or more physical processors, and/or other components. The distancing device may be configured to generate output signals conveying position information. The position information may include positions of surfaces of real-world objects, including surfaces of a human hand. A group of points may be identified that lie on a candidate surface which is a candidate for being the surface of a hand. The edges of the candidate surface may be detected. The points furthest away from the closest edge may be determined. A model may be created by connecting at least some of these points. Sections of the model are identified that may be a digit of the hand. Per section, fingertips and metacarpophalangeal joints may be identified. The model may be analyzed to determine whether the candidate surface is the surface of a hand.

  • Patent number: 10204157
    Abstract: A fingerprint of an image identified within a received message is generated following analysis of the message. A spam detection engine identifies an image within a message and converts the image into a grey scale image. The spam detection engine analyzes the grey scale image and assigns a score. A fingerprint of the grey scale image is generated based on the score. The fingerprint may also be based on other factors such as the message sender's status (e.g. blacklisted or whitelisted) and other scores and reports generated by the spam detection engine. The fingerprint is then used to filter future incoming messages.

    Abstract: In a method of extracting a logo mask from a video stream having a logo, a video stream including a plurality of frames is received. A plurality of online-weighted-average frames is sequentially generated using the video stream. A logo-boundary-score map is generated using a current frame among the plurality of frames and a current online-weighted-average frame among the plurality of online-weighted-average frames. The logo-boundary-score map includes a plurality of logo-boundary-score entries, each of which corresponds to one of a plurality of pixels of the video stream and includes a probability that a corresponding one of the plurality of pixels is a logo-boundary pixel. The logo mask includes a plurality of entries, each of which corresponds to one of the plurality of pixels and represents whether a corresponding one of the plurality of pixels is a logo pixel or a non-logo pixel.
