Abstract

A method and apparatus for finite impulse response (FIR) filter bank architecture and method that involve low-complexity computation resources are described. In one embodiment, a digital image processing system includes an index mapping module to determine a rotation angle index to control rotation of an input patch of an image based on the (x,y) pixel coordinates of the image patch. The digital image processing system may also include a rotation module to rotate the input patch of the image based on the rotation angle index. In one embodiment, the digital image processing system may further include a filter engine module applied to a rotated version of the input patch of the image.
