Systems and methods of blurring images may involve partitioning at least a portion of a non-separable finite impulse response (FIR) filter into a plurality of constant response sub-filters, wherein each constant response sub-filter has a rectangular aperture. In addition, the plurality of constant response sub-filters may be used to blur an image. In one example, the non-separable FIR filter may optionally be partitioned into one or more satellite sub-filters, wherein the one or more satellite sub-filters are also used to blur the image.
