METHOD AND DEVICE FOR VIDEO ENCODING BASED ON LONG-TERM REFERENCE FRAME, COMPUTING DEVICE AND DATA CARRIER Russian patent published in 2023 - IPC H04N19/146 

FIELD: image processing technology.

SUBSTANCE: invention relates to video coding based on a long-term reference frame. The method includes the following steps: setting the long-term reference frame according to the attribute information of the image frame; determining a reference index for an image frame to be encoded based on the normal reference frame and the long-term reference frame; and obtaining a target matching block by performing inter-prediction based on the reference index to encode an image frame to be encoded; wherein adjusting the long-term reference frame according to the attribute information of the image frame includes the step of adjusting the long-term reference frame based on the redundancy rate in the time domain and the redundancy rate in the spatial domain for the image frame.

EFFECT: increasing the efficiency of video compression.
