Abstract

The invention discloses a self-adaptive scalable video coding and decoding structure design method which is based on a region of interest and a scalable video coding and decoding technical system architecture of the region of interest (ROI); the content of a video is segmented by a self-adaptive video segmentation and tracking technology, thereby realizing the separation of the region of interest(ROI) from a background; the time-domain redundancy is eliminated by a regional motion compensation time-domain filter technology of the ROI; information of the region of interest (ROI) can be coded and transmitted prior to the background region by a ROI self-adaptive bit plane lifting technology of regional wavelet, thereby obtaining better visual effect under the low code rate; a regional time-frequency domain factor carries out the distinction between the region of interest (ROI) and the background by a regional self-adaptive template technology; and the self-adaptive code rate distribution of the region of interest (ROI) and the background is realized by a regional self-adaptive code rate control technology.

Description

Design Method of Adaptive Scalable Video Codec Structure Based on Region of Interest technical field The invention belongs to the field of video coding and decoding, and in particular relates to an adaptive and scalable video coding and decoding structure design method based on regions of interest. Background technique With the continuous popularization and development of the Internet and wireless communication, the fluctuation of bandwidth, the diversity of user terminals and the heterogeneity of the network put forward higher requirements for video streaming services. Traditional video coding standards are facing new challenges because they cannot flexibly adapt to transmission conditions and the diversity of customer needs. The previous video codec technology cannot dynamically adjust the code stream, and cannot maximize the use of bandwidth resources. When the network transmission conditions are poor, the user may not be able to receive the video at the terminal, and w...
