WARPING PARAMETER SIGNALING FOR IMAGE STABILIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18434557 titled 'WARPING PARAMETER SIGNALING FOR IMAGE STABILIZATION
Simplified Explanation
The patent application describes a method, apparatus, and computer-readable storage medium for video decoding, specifically focusing on a warping process applied to decoded pictures based on supplemental enhancement information (SEI) messages.
- The processing circuitry decodes a current picture from a bitstream.
- It determines from an SEI message whether a warping process is applied to the current decoded picture.
- If the warping process is applied, the circuitry determines warping information from the SEI message.
- It then generates a warped picture from the current decoded picture based on the warping information.
Potential Applications
This technology could be applied in video streaming services, virtual reality applications, and video conferencing systems.
Problems Solved
This technology solves the problem of efficiently applying warping processes to decoded pictures in video decoding systems.

Original Abstract Submitted
Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry that is configured to decode a current picture based on a bitstream. The processing circuitry can determine, from a supplemental enhancement information (SEI) message, a first flag indicating whether a warping process is applied to the current decoded picture. Based on the first flag indicating that the warping process is applied to the current decoded picture, the processing circuitry can determine warping information of the warping process based on the SEI message. The processing circuitry can determine a warped picture from the current decoded picture based on the warping information.
