Claim 0:
1. An image filtering apparatus for filtering an input image, the image filtering apparatus comprising:
a loop filter that includes (i) at least a first neural network filter and a second neural network filter, and (ii) an adaptive loop filter,
wherein:
the first neural network filter receives (i) the input image and (ii) an image of a quantization parameter which is defined by an array of two dimensions, and outputs a first output image,
the second neural network filter receives the input image or the first output image, and outputs a second output image, and
the adaptive loop filter receives (i) the input image, (ii) the first output image, and (iii) the second output image, and outputs a filtered image, as a third output image.
