4. def apply(shape: libcog.Shape, channels: Int): Array[libcog.Matrix]

   

   Create a set of directional filters in the frequency domain.

   Create a set of directional filters in the frequency domain.

   shape

   Shape of the images to be processed by the filterbank.

   channels

   Number of channels (directions) supported by the filterbank. Legal values are 2, 4, 8.

   returns

   An array of filters, one per channel, in the frequency domain. Each filter will have the shape shape. The filters are zero-phase, so they are represented with matrices rather than complex matrices.
