Claim 6:
7. An apparatus comprising:
one or more processors configured to encode video data based on a prediction loop based encoding process comprising:
applying a mapping to a picture part using a mapping function to obtain a mapped picture part;
encoding the mapped picture part based on a reference picture to provide an encoded picture part;
reconstructing and in-loop filtering in the prediction loop the encoded picture part to provide a filtered reconstructed picture part;
applying an inverse of the mapping function to the filtered reconstructed picture part to obtain an inverse mapped filtered reconstructed picture part;
determining a refinement based on the inverse mapped filtered reconstructed picture part;
encoding data representing the refinement in the form of parameters representative of a piece wise linear model to provide encoded refinement data; and
providing video data including the encoded picture part and the encoded refinement data.
