Abstract: A method for eye tracking in a head-mountable device (HMD) includes determining at least one object within a three-dimensional (3D) extended reality (XR) environment as an eye tracking calibration point and determining a 3D location of the eye tracking calibration point within the XR environment. The method also includes detecting a gaze point of a user of the HMD and comparing the detected gaze point to an area of the XR environment that includes the 3D location of the eye tracking calibration point. The method further includes, in response to determining that the user is looking at the eye tracking calibration point based on the detected gaze point being within the area, calibrating, using a processor, the HMD to correct a difference between the eye tracking calibration point and the detected gaze point. In addition, the method includes, in response to determining that the user is not looking at the eye tracking calibration point based on the detected gaze point being outside of the area, maintaining an existing calibration of the HMD.

Abstract: A method, apparatus, and computer readable medium for interactive cinemagrams. The method includes displaying a still frame of a cinemagram on a display of an electronic device, the cinemagram having an animated portion. The method also includes after the displaying, identifying occurrence of a triggering event based on an input from one or more sensors of the electronic device. Additionally, the method includes initiating animation of the animated portion of the cinemagram in response to identifying the occurrence of the triggering event. The method may also include generating the image as a cinemagram by identifying a reference frame from a plurality of frames and an object in the reference frame, segmenting the object from the reference frame, tracking the object across multiple of the frames, determining whether a portion of the reference frame lacks pixel information during motion of the object, and identifying pixel information to add to the portion.

Abstract: A method includes processing, using at least one processor of an electronic device, multiple reference images of a scene using a first convolutional neural network (CNN) to generate a confidence map and a disparity map. The method also includes generating, using the at least one processor, an initial Bokeh image based on the disparity map and the reference images using a depth-of-field (DoF) renderer. The method further includes refining, using the at least one processor, the initial Bokeh image using a second CNN to generate a refined Bokeh image, where the second CNN uses the confidence map, the disparity map, and the reference images to generate the refined Bokeh image.

Abstract: A method includes, in a first mode, positioning first and second tiltable image sensor modules of an image sensor array of an electronic device so that a first optical axis of the first tiltable image sensor module and a second optical axis of the second tiltable image sensor module are substantially perpendicular to a surface of the electronic device, and the first and second tiltable image sensor modules are within a thickness profile of the electronic device. The method also includes, in a second mode, tilting the first and second tiltable image sensor modules so that the first optical axis of the first tiltable image sensor module and the second optical axis of the second tiltable image sensor module are not perpendicular to the surface of the electronic device, and at least part of the first and second tiltable image sensor modules are no longer within the thickness profile of the electronic device.

Abstract: A method includes obtaining at least one image and a ground truth map associated with the at least one image. The method also includes generating multiple optical maps using multiple algorithms and the at least one image. The method further includes, for each algorithm, identifying at least one score for the algorithm using one or more of the optical maps generated using the algorithm and the ground truth map. The ground truth map identifies one or more boundaries associated with one or more foreground objects in the at least one image. The scores identify how well the optical maps generated using the algorithms separate the one or more foreground objects from a background in the at least one image.
