Abstract: A viewing direction may define an angle/visual portion of a spherical video at which a viewing window is directed. A trajectory of viewing direction may include changes in viewing directions for playback of spherical video. Abrupt changes in the viewing directions may result in jerky or shaky views of the spherical video. Changes in the viewing directions may be stabilized to provide stabilized views of the spherical video. Amount of stabilization may be limited by a margin constraint.

Abstract: Apparatus and methods for optimized stitching of overcapture content. In one embodiment, the optimized stitching of the overcapture content includes capturing the overcapture content; producing overlap bands associated with the captured overcapture content; downsampling the produced overlap bands; generating derivative images from the downsampled overlap bands; generating a cost map associated with the generated derivative images; determining shortest path information for the generated cost map; generating a warp file based on the determined shortest path information, the generated warp file being utilized for the optimized stitching of the overcapture content. Camera apparatus and a non-transitory computer-readable apparatus are also disclosed.

Abstract: Methods and apparatus for shear correction in spherical projections. Embedded devices generally lack the compute and/or memory resources to implement two-dimensional (2D) stitches for spherical projections. Objects (such as a mounting fixture) within a certain distance of the camera may experience a 2D “tear” or “shear” artifact when stitched. Various embodiments of the present disclosure perform two orthogonal 1D stitches: (i) latitudinally across the meridian and (ii) longitudinally along the meridian to approximate the effect of a 2D stitch. Notably, the 1D stitch may be less precise than a true 2D stitch, however the image portion being stitched (e.g., the camera mount) is not the user's subject of interest and can be rendered much more loosely without adverse consequence. Temporal smoothing optimizations are additionally disclosed.

Abstract: Positions of an image capture device during capture of a video may be transferred to a computing device before the video is transferred to the computing device. The positions of the image capture device may be used to determine a viewing window for the video before the video is obtained. The viewing window may be used to present a stabilized view of the video when the video is obtained. For example, a stabilized view of the video may be presented as the video is streamed to the computing device.

Abstract: Apparatus and methods for the non-uniform downsampling of captured panoramic images. In one embodiment, a computing device is disclosed that includes a processing apparatus and a non-transitory computer readable apparatus comprising a storage medium have one or more instructions stored thereon. The one or more instructions, when executed by the processing apparatus, being configured to: receive captured images, the captured images obtained using two or more image sensors; non-uniformly downsample the received captured images; and encode the non-uniformly downsampled images. In some variants, the non-uniformly downsampled images take into account a desired area of interest within the captured images. In some implementations, the computing device includes an image capture device. Methods and non-transitory computer readable apparatus are also disclosed.

Abstract: Methods and apparatus for processing of video content to optimize codec bandwidth. In one embodiment, the method includes capturing panoramic imaging content (e.g., a 360° panorama), mapping the panoramic imaging content into an equi-angular cubemap (EAC) format, and splitting the EAC format into segments for transmission to maximize codec bandwidth. In one exemplary embodiment, the EAC segments are transmitted at a different frame rate than the subsequent display rate of the panoramic imaging content. For example, the mapping and frame rate may be chosen to enable the rendering of 8K, 360° content at 24 fps, using commodity encoder hardware and software that nominally supports 4K content at 60 fps.

Abstract: Depiction of a physical whiteboard may be captured by an image capture device. The depiction of the physical whiteboard may be detected and used to generate a virtual whiteboard. A change in the depiction of the physical whiteboard may be detected and used to change the virtual whiteboard. A virtual change to the virtual whiteboard may be received and used to change the virtual whiteboard. The change to the virtual whiteboard based on the virtual change may be projected on top of the physical whiteboard.

Abstract: Multiple framings of a video may define different positionings of a viewing window at different moments within the video.

The viewing path may define changes in the positioning of the viewing window between the fixed positionings. A presentation of the video may be generated to include the extents of the video within the viewing window.

Abstract: Methods and apparatus for stabilizing image data based on a lens polynomial. Non-rectilinear footage can be captured and rectified in-camera; the rectified images may be stabilized to provide rectified stable video. In one exemplary embodiment, the footage is rectified and stabilized based on a lens polynomial and the camera's own movement. In some variants, the rectified stable video may be stored along with its margin track. In-camera rectified stable video provides several benefits over traditional techniques (e.g., the ability to share rectilinear content from the camera without additional post-processing, as well as reduced file sizes of the shared videos). Lens-aware post-processing can reuse portions of the in-camera rectified stable videos while providing additional benefits (e.g., the ability to re-frame the video in post-production).

Abstract: A video may be captured by an image capture device in motion. A stabilized view of the video may be generated by providing a punchout of the video. The punchout of the video may compensate for rotation of the image capture device during capture of the video. The size of the punchout of the video may be changed based on different rotational positions of to provide a view that includes different extents of the captured visual content. The changes in the size of the punchout may simulate changes in zoom of the visual content.
