Abstract

The embodiment of the invention provides a video filtering method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the filtering of a to-be-filtered image through employing a filter corresponding to a specified multi-group filtering intensity combination, obtaining a plurality of real distortion results of the to-be-filtered image, and taking the result as a real distortion result corresponding to each set of specified filtering intensity combination; fitting a preset intensity distortion model to obtain model parameters of the intensity distortion model; calculating to obtain analog distortion values of all filtering intensity combinations for filtering the to-be-filtered image; determining a filtering intensity combination corresponding to the obtained minimum analog distortion value as a target filtering intensity combination; and carrying out filtering processing on the to-be-filtered image by using the target filtering intensity combination so as to realize filtering processing on the to-be-filtered video. By adopting the method, the calculation complexity of video filtering is reduced.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video filtering method, device, electronic equipment and storage medium. Background technique [0002] The new-generation video standard AV1 (AOMedia Video 1) mainly uses CDEF (Constrained Directional Enhancement Filter) technology for video filtering. The CDEF filtering process may specifically include: performing a filter test of each intensity on the image to be filtered of the video to be filtered, and then performing filtering according to the filter intensity parameter pair with the least distortion of the test result. [0003] However, since CDEF filtering requires filtering tests for all filter strengths, that is, it is necessary to perform filter tests for each strength of each image to be filtered, in order to determine the optimal filter strength parameter pair for filtering. This leads to high computational complexity of CDEF filtering. Contents ...
