  • Patent number: 12367680
    Abstract: A single credential capture event enables a plurality of persons to transit a physical access control portal. A cohort is determined when each of a plurality of persons is found within an identity indicia store. When a credential for any one of the cohort is validated, a physical access control actuator is enabled. A video stream of the plurality of persons is transformed to a plurality of best face images. When each one of the best face images is correlated with an entry in the identity indicia store above a threshold, a potential validation window is opened for the cohort. When a credential event for any of the plurality of persons occurs within the validation window, admittance is enabled through the physical access control portal. A cohort is a contiguous sequence of persons which begins with a first correlated best face and is terminated before the first uncorrelated best face.

  • Patent number: 12329129
    Abstract: A method of counting pigs or poultry includes mounting a camera at an alleyway through which the livestock pass with a width such that the livestock can pass at least two abreast and are free to turn to move in an opposite direction against the direction of travel before all livestock of the group complete their movement though the alleyway. An analysis of the images is carried out which takes into account errors caused by livestock which turn in the portion of the alleyway to move in the opposite direction temporarily before continuing to complete the travel through the portion of the single alleyway to the remote location and takes into account errors caused animals being side by side when passing through the portion of the single alleyway.

  • Patent number: 12333766
    Abstract: A method for training a depth estimation model is provided. The method includes obtaining a first left image and a first right image. A disparity map is obtained by inputting the first left image into a depth estimation model. A second right image is obtained by adding the first left image to the disparity map. The first left image is converted into a third right image. A mask image is obtained by performing a binarization processing on a pixel value of each of pixel points of the third right image. Once a loss value of the depth estimation model is obtained by calculating a mean square error of pixel values of all corresponding pixel points of the first right image, the second right image, and the mask image, a depth estimation model is iteratively trained according to the loss value.

  • Patent number: 12322131
    Abstract: A method of displaying a digital object on a device is disclosed. A set of unique identifiers and associated is downloaded for a set of digital objects within a 3D model. A position and an orientation of a virtual camera is determined relative to the positions of the set of digital objects. A visibility score for each digital object of the set of digital objects is computed based on a position of the digital object relative to the position and the orientation of the virtual camera. A polygon mesh associated with a digital object with a highest visibility score is downloaded based on the polygon mesh being absent. The downloading uses a unique identifier of the set of unique identifiers associated with the polygon mesh. The polygon mesh of the digital object with the highest score is rendered and displayed on a display device.

  • Patent number: 12277789
    Abstract: A Smart Optical Character Recognition (SOCR) Trainer comprises software developed for automating Quality Control (QC) using unsupervised machine-learning techniques to analyze, classify, and optimize textual data extracted from an image or PDF document. SOCR Trainer serves as a ‘data treatment’ utility service that can be embedded into data processing workflows (e.g., data pipelines, ETL processes, data versioning repositories, etc.). SOCR Trainer performs a series of automated tests on the quality of images and their respective extracted textual data to determine if the extraction is trustworthy. If deficiencies are detected, SOCR Trainer will analyze certain parameters of the document, perform conditional optimizations, re-perform text extraction, and repeat QA testing until the output meets desired specifications. SOCR Trainer will produce audit files recording the provenance and differences between original documents and enhanced optimized document text.
