Abstract: This paper describes efficientschemes for the computation of a large number of differentely scaled/oriented
filtered versions of an image. We generalize the well-known steerable/scalable ("deformable") filter bank
structure by imposing X-Y separability on the basis filters. This systems, designed by an iterative
projections technique, achieve substantial reduction of the computational cost. (Update)

...decomposition. Perona [4] studied the conditions for a kernel d(x; with continuous x and ) to be exactly steerable. One easily shows [7] that steerable filters are formally equivalent to multistage X Y separable structures, introduced by Treitel and Shanks [6] As in the...
...matrix depends on the dimensions of the matrix hence does not scale well. Another example is in the construction of steerable filters [5, 3, 4]. Given a filter OE(x; y) and a set of transformations T , the task is to find a set of basis filters Phi = fOE 1 ; OE k g...
