Various embodiments herein provide techniques for Session Description Protocol (SDP)-based signaling of camera calibration parameters for multiple video streams. In embodiments, a device may receive an SDP attribute to indicate that a bitstream included in a real-time transport protocol (RTP)-based media stream includes camera calibration parameters. The device may obtain the camera calibration parameters based on the SDP attribute, and process the RTP-based media stream based on the camera calibration parameters. In embodiments, the camera calibration parameters may be used to stitch together (e.g., align and/or synchronize) the multiple video streams. In embodiments, the stitched video streams may form an immersive video content (e.g., 360-degree video content). Other embodiments may be described and claimed.

Session description protocol (SDP) based signaling of camera calibration

An apparatus and method for efficient image optimized image stitching. For example, one embodiment of an apparatus comprises: feature search area identification circuitry/logic to narrow down a feature search area based on possible overlap between two image frames; feature detection circuitry/logic to identify a plurality of feature points in a first image frame of the two image frames; feature matching circuitry/logic to map one or more of the plurality of feature points from the first image frame to corresponding feature points in the right image frame; image frame stitching and blending circuitry/logic to stitch the first image frame and second image frame based on the mapping of the feature points between the two image frames and to blend a portion of the first image frame with a portion of the second image frame.

Apparatus and method for optimized image stitching based on optical flow

A method, corresponding apparatuses, and a non-transitory computer readable medium for image processing are provided. A method comprises selecting at least one reference point on a sensor illumination response curve in a sensor illumination response plane. The method further comprises determining at least one dominant color evaluation region in the sensor illumination response plane based on the at least one reference point.
