Solution Overview

Problem

Existing video frame compression methods relying on neural networks accumulate errors frame by frame due to excessive dependence on the quality of the decompressed reference frame, leading to degraded reconstruction quality.

Innovation Solution

A method that utilizes a combination of multiple neural networks, where one network generates features independently of the reference frame and another network uses the reference frame for feature generation, minimizing data transmission while improving reconstruction quality by reducing error accumulation.

Solution Approach 1:

The patent divides the compression system into two independent neural networks: a first neural network that processes current video frames independently without reference frames, and a second neural network that uses reference frames for compression. This segmentation allows each network to operate autonomously, preventing error accumulation while maintaining compression efficiency through specialized functionality.

AI summary

A video frame compression method includes determining a target neural network from a plurality of neural networks according to a network selection policy; and generating, by using the target neural network, compression information corresponding to a current video frame. If the compression information is obtained by using a first neural network, the compression information includes first compression information of a first feature of the current video frame, and a reference frame of the current video frame is used for a compression process of the first feature of the current video frame. If the compression information is obtained by using a second neural network, the compression information includes second compression information of a second feature of the current video frame, and a reference frame of the current video frame is used for a generation process of the second feature of the current video frame.
