Patent ID: 8908979

Claim:
An apparatus comprising: an image processing circuitry including: a video/image encoder configured to design a two-dimensional star-shaped spatial filter and encode image/video information using the star-shaped spatial filter, the star-shaped spatial filter comprising: a first linear arrangement of coefficients that extend outwardly in a first diagonal direction from a center pixel coefficient; a second linear arrangement of coefficients that extend outwardly in a second diagonal direction from the center pixel coefficient; a third linear arrangement of coefficients that extend outwardly in a horizontal direction from the center pixel coefficient; and a fourth linear arrangement of coefficients that extend outwardly in a vertical direction from the center pixel coefficient, wherein the second diagonal direction is oriented in a different direction relative to the first diagonal direction, and wherein at least one of a first coefficient and a second coefficient of the star-shaped spatial filter comprise point symmetry about the center pixel coefficient.
