Abstract

A loop filtering method and device are provided. By optimizing the encoding method in the process of encoding and decoding loop filtering, the calculation complexity of loop filtering is reduced, the calculation speed is accelerated, and the encoding and decoding performance is improved. A loop filtering method includes determining multiple sets of filter coefficients for a loop filter, and encoding the multiple sets of filter coefficients by using a non-differential encoding method. Another loop filtering method includes determining a clip index parameter of a loop filter, and encoding the clip index parameter by using a non-exponential Golomb encoding method. Still another loop filtering method includes determining a loop filter clip parameter of a brightness component and a loop filter clip parameter of a chrominance component of an image frame, where the loop filter clip parameter of the brightness component and the loop filter clip parameter of the chrominance component are parameters selected from the same parameter list.
