    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 post-processing in-camera stabilized video. Embodiments of the present disclosure reconstruct and re-stabilize an in-camera stabilized video to provide for improved stabilization (e.g., a wider crop, etc.) In-camera sensor data may be stored and used to re-calculate orientation metadata in post-production. In-camera stabilization provides several benefits (e.g., the ability to share stabilized videos from the camera without additional post-processing as well as reduced file sizes of the shared videos). Camera-aware post-processing can reuse portions of the in-camera stabilized videos while providing additional benefits (e.g., the ability to regenerate the original captured videos in post-production and re-stabilize the videos). Camera-aware post-processing can also improve orientation metadata and remove sensor error. The disclosed techniques also enable assisted optical flow-based stabilization using the refined metadata.

    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).
