Apparatus and methods for embedding metadata into video stream
TLDR
In this paper, the metadata is stored in a track in a self-describing structure and the metadata track may be decoded using an identifier reference table that is substantially smaller than typical fourCC identifier tables.Abstract:
Apparatus and methods for combining metadata with video into a video stream using a 32-bit aligned payload, that is computer storage efficient and human discernable. The metadata is stored in a track in a self-describing structure. Metadata track may be decoded using an identifier reference table that is substantially smaller than typical fourCC identifier tables. The combined metadata/video stream is compatible with a standard video stream convention and may be played using conventional media player applications that reads media files compliant with MP4/MOV container format. The proposed format may enable decoding of metadata during streaming, partitioning of combined video stream without loss of metadata. The proposed format and/or metadata protocol provides for temporal synchronization of metadata with video frames.read more

Apparatus and methods for compressing video content using adaptive projection selection
TL;DR: In this paper, a panoramic image may be mapped to a cube, equirectangular or any other projection e.g., icosahedron or octahedron.
Patent
Watermarking digital images to increase bit depth
TL;DR: Watermark data is converted to watermark coefficients, which may be embedded in an image by converting the image to a frequency domain, embedding the watermark in image coefficients corresponding to medium-frequency components, and converting the modified coefficients to the spatial domain this article.

Method and system for compensating for parallax in multiple camera systems
TL;DR: In this paper, a camera array captures plural component images which are combined into a single scene in one embodiment, each camera of the array is a fixed digital camera The images from each camera are warped to a common coordinate system and the disparity between overlapping images is reduced using disparity estimation techniques.
Patent
Systems and methods for suggesting meta-information to a camera user
TL;DR: In this paper, a camera captures an image and sends it to a server for image recognition processing, where the camera receives information from the server, including an indication of information to suggest to a user for meta-tagging the image.

Embedded metadata engines in digital capture devices
TL;DR: In this article, a real-time content-based analysis function in the capture device is used to extract metadata from the digital signals, which are then combined with the digital content in a container format such as MPEG-7, QuickTime, or FlashPix.
