Improved process for multi-eyepoint video encode based on HHI layered B frame predict structure

Abstract

The invention discloses an improvement method for multi-view video coding based on HHI hierarchical B picture prediction structure, belonging to the technical field of video coding. The method improves the inter-frame prediction part, and the processing modes for other parts are the same with the methods in MVC reference software. The method comprises the following two parts: (1) whether each macro block of the non-key frame of the B picture chooses an adjacent viewpoint frame as a reference frame during the inter-frame prediction; (2) when an inter-frame prediction based on macro block is performed, judgment is made to determine whether each macro block needs a small size partition mode inter-frame prediction. The method has the advantages that, each macro block in a frame waiting for coding can effectively choose a reference frame, and the partition mode of the macro block is limited; unnecessary small size partition mode inter-frame prediction of some macro blocks is reduced, and the time complexity of coding is greatly lowered.

AI Technical Summary

Benefits of technology

This technology improves how videos captured by cameras work better than older methods like film or digital still camera recordings. By utilizing neighboring views instead of just one frame for comparison between them, less computationally effort is needed compared to existing techniques. Additionally, this method allows for more efficient selection of relevant ones based on their importance during compression rather than simply selecting representative blocks. Overall, these improvements improve efficiency over previous methods while reducing computational resources required.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the efficient processing of videos captured through multiple devices such as monitors or televisions without sacrificial resources like memory capacity. Current proposals involve simplifying the process of compressing images before transmitting over networks, but current approaches only consider how much detail remains within individual blocks of pixels. These techniques aim towards more accurate depth perception and improved visual quality during playback.
