Abstract
There is provided a method for encoding one or more images. The method comprises filtering, with a first filter, input samples I(x,y) to generate a first filtered output Ifirst(x,y)=I(x,y)+ΔIfirst(x,y). The method comprises estimating parameters for a second filter based at least in part on the first filtered output Ifirst(x,y), the input samples I(x,y), and original samples Iorig(x,y). The method comprises filtering, with the second filter, input samples I(x,y) to generate a second filtered output Isecond(x,y)=I(x,y)+ΔIsecond(x,y), wherein filtering, with the second filter, is based at least in part on the parameters estimated for the second filter. The method comprises generating a combined output ICOMB(x,y)=I(x,y)+ΔIfirst(x,y)+ΔIsecond(x,y).
