Abstract
A method and an apparatus for sample adaptive offset, a device, and a medium are provided. An implementation is: obtaining a band value and a residual of each pixel in a target image; selecting a plurality of adjacent target pixels from the target image; and performing band information calculation operation for the plurality of adjacent target pixels, the band information calculation operation including: obtaining a maximum band value and a minimum band value of the plurality of target pixels; determining a plurality of preset band values based on the maximum band value and the minimum band value; and calculating band information for each of the plurality of preset band values based on the band values and the residuals of the plurality of target pixels.
