Abstract
A simplified parametric loop filter uses a set of fixed filters to remove or reduce noise and artifacts introduced during video coding. The simplified parametric loop filter uses the parameters such as direction and bandwidth to uniquely identify a fixed filter from the set of filters. The simplified parametric loop filter implements symmetry between filters, symmetry within each filter, unity DC gain and zero-forcing to 1) reduce the storage space in memorizing the fixed filters, and 2) reduce the computational complexity for performing filtering.
