| Popis: | The steerable pyramid decomposition is an invertible representation similar to the two-dimensional discrete wavelet transform, but with interesting shift- and rotation-invariance properties. It is slightly overcomplete and amenable to a filter bank implementation via convolution and down- and up-sampling operations. This paper presents a simple method for designing the FIR filter kernels required to implement the transform. |
