ABSTRACT:
A filter includes a plurality of one-dimensional first dimension filters operating in a first dimension, each of the filters operating on the digital image data in accordance with predetermined filter coefficients to produce a one-dimensional output signal. The filter also includes a plurality of one-dimensional filters, operating in a second, distinct dimension, each one-dimensional second dimension filter receiving output signals from one of the plurality of the first dimension filters and operating on the received output signals in accordance with predetermined filter coefficients to produce second filtered output signals therefrom. A weighting circuit is operatively connected to the one-dimensional second dimension filters to modify each of the produced second filtered output signals according to weighting coefficients.
