  • Patent number: 11908153
    Abstract: A system and method for measuring distances related to a target object depicted in an image. A captured digital image is obtained containing a scene with a target object whose dimension is to be measured. The digital image may contain a target object dimension identified by one or more ancillary objects and a reference object in the same or different planes. Image processing is performed to find the reference object using known fiducial patterns printed on the reference object, metadata supplied by a user and/or by the detection of colored papers in the scene of the captured image. Once located and measured, the reference object is used to calculate a pixel scale factor used to measure the target object dimensions. Target object dimensions are provided to an automated or semi-automated measurement process, design and manufacturing system such that customized parts for a supplemental fenestration are provided to end users.

  • Patent number: 11880961
    Abstract: Techniques are described for the inpainting of an image with a missing region. In an embodiment, the process transforms an input image tensor of the image into a spectral tensor of the image. A machine learning-generated filter is applied to the spectral tensor of the image. Additionally or alternatively, a spectral tensor is spectrally split into at least high-frequency and low-frequency sub-tensors. The output tensor(s) are then inverse-transformed into the spatial domain, yielding pixel data for the unknown region that accurately regenerates both low-level detail information as well as high-level detail information.

  • Patent number: 11867668
    Abstract: The present disclosure describes systems and methods to correct for perspective calibration variations of a variable thickness specimen with a single camera extensometer in a video extensometer system. In some examples, the systems and methods compensate for a change between a reference characteristic, such as a calibration plane, and an actual physical characteristic, such as a testing plane associated with a surface of a test specimen, during a testing operation. In some examples, a correction value is applied to an output (e.g., measured dimensions of the imaged test specimen) to compensate for the difference between the reference characteristic and the physical characteristic.

  • Patent number: 11836900
    Abstract: The technique of the present disclosure can add a gloss to image data according to the hair flow of a subject. An image data obtaining unit obtains input image data, and a characteristic amount calculating unit calculates characteristic amounts for the input image data. The characteristic amount calculating unit obtains a degree to which directions of hair flow are concentrated to a predetermined direction (a degree of alignment) in a predetermined range based on the directions of hair flow, and sets this as a characteristic amount indicative of the degree of alignment of the directions of hair flow. A determining unit estimates the state of the hair flow of the entire input image data based on the characteristic amounts thus calculated, and determines whether to correct the input image data. A correcting unit performs a gloss adding correction to the input image data.

  • Patent number: 11823499
    Abstract: Interactive based on said set steps of authentication methods for the recognition of a person. During authentication, a previously stored enrollment image is presented on a display to the person. A candidate person is instructed to present a reproduced image of the same scene and/or object to a camera while the person is holding the camera (mobile camera for example) unsupported in free space with respect to the scene or object. Alternatively the user can hold the object unsupported in free space with respect the camera using the camera, a candidate image of the viewed scene or object is captured and presented with the previously stored enrollment image. The candidate person aligns the candidate image with the previously stored enrollment image. On alignment, the candidate image is verified as an authentic image of the person and the candidate person is authenticated as the person previously enrolled.

  • Patent number: 11804077
    Abstract: A generic gesture detecting method executed by a generic gesture detecting device includes steps of: receiving a current sensing signal from a sensing unit; generating a current image according to the current sensing signal; determining whether the current image is similar with a stored image stored in a memory unit; when the current image is similar with the stored image, detecting the current image and the stored image to be a gesture signal; when the current image is different from the stored image, storing the current image into the memory unit, and returning to the step of receiving a current sensing signal. Since the generic gesture detecting device can automatically detect the gesture signal, the user may not need to enable a detecting time period before implementing a command motion. Therefore, the user can make the command motion without enabling the detecting time period, and the convenience can be increased.
