  • Publication number: 20240112315
    Abstract: A method for processing a stream of input images is provided. The method includes receiving a stream of input images, and applying a digital effect to the stream of input images. The digital effect is one or more from the group of: a pan, a tilt, or a zoom, of the stream of input images. The method further includes selecting an analytical projection type, from a plurality of analytical projection types, that maps pixels of the input stream of images to projected pixels of a modified stream of images, generating the modified stream of images, using the selected analytical projection type, thereby correcting a geometric distortion within the stream of input images, while applying the digital effect, and displaying the modified stream of images.

  • Publication number: 20230230210
    Abstract: One disclosed example provides a videoconferencing system comprising a processor and a storage device storing instructions executable by the processor to obtain an image of a scene acquired via a camera, the image of the scene comprising image distortion arising from a camera pitch angle at which the image of the scene was acquired. The instructions are further executable to apply a projection mapping to the image of the scene to map the image of the scene to a projection comprising a tilt parameter that is based upon the camera pitch angle at which the image of the scene was acquired, thereby obtaining a corrected image, and output the corrected image.

  • Patent number: 11663704
    Abstract: Examples are disclosed relating to applying an analytical geometric projection that has been modified by an amplitude function. One example provides a computing device comprising a logic subsystem and a storage subsystem holding instructions executable by the logic subsystem to receive an image of a scene as acquired by an image sensor, apply a mapping to the image of the scene that maps pixels of the image to projected pixels on an analytical projection that is modified by an amplitude function such that the analytical projection achieves a higher zoom effect on pixels closer to a center of the image compared to pixels closer to an edge of the image, thereby obtaining a corrected image, and output the corrected image.

  • Publication number: 20230116036
    Abstract: Systems and methods are provided for calibrating camera and measuring offsets for reducing distortions on images. The calibrating includes aligning an on-board image sensor and a lens barrel using a kinematic mount and affixing the onboard image sensor and the lens barrel to assemble a camera. The kinematic mount provides a predetermined number of degrees of freedom in aligning the on-board image sensor and the lens barrel. A device embeds the camera. The measuring includes receiving the camera in the kinematic mount and measuring an opposing pair of offset values as measured optical centers from the lens optical axis to the image sensor pointing reference at yaw orientations of the camera at 0 degree and 180 degrees. The method determines a total offset value by taking an average of the pair and canceling the rotationally symmetrical error. The method uses the offset value for reducing distortions on images by de-warping.

  • Publication number: 20230049680
    Abstract: An anterior lumbar interbody fusion device comprising a superior component, an inferior component, and a locking mechanism. The superior component bottom side and the inferior component top side oppose each other when these are received in the intervertebral space whereby their external sides abut against the respective vertebra, thereby coupling force between the latter. The components inter-engage with each other whereby they are constrained to move in an anterior-posterior direction relative to each other and resistance is presented to movement relative to each other in each of a direction of separation and a direction orthogonal to the anterior-posterior direction and to the direction of separation.

  • Publication number: 20230038323
    Abstract: An intervertebral fusion device comprises a superior component, an inferior component, and a core component. The superior and inferior components are received between first and second vertebrae whereby a superior component top side of the superior component abuts against the first vertebra, and an inferior component bottom side of the inferior component abuts against the second vertebra. The core component is inserted between the superior and inferior components to determine a height of the intervertebral fusion device. First and second core profiles of the core component cooperate respectively with a first component profile of the superior component and a second component profile of the inferior component during insertion of the core component to guide the core component relative to the superior and inferior components.

  • Publication number: 20220414819
    Abstract: A method for processing a stream of input images is described. A stream of input images that are from an image sensor is received. The stream comprises an initial sequence of input images including a subject having an initial orientation. A change in an angular orientation of the image sensor while receiving the stream of input images is determined. In response to determining the change in the angular orientation, a subsequent sequence of input images of the stream of input images is processed for rotation to counteract the change in the angular orientation of the image sensor and maintain the subject in the initial orientation. The stream of input images is transmitted to one or more display devices.
