On Symmetric Extensions, Orthogonal Transforms of Images, and Paraunitary Filter Banks
Periodic or symmetric extensions are commonly used for processing images and other finitelength signals with a paraunitary Alter bank (PUFB).Unlike infinite-length signals, PUFBs ...

Three-dimensional feature detection using optimal steerable filters
We present a framework for feature detection in 3-D using steerable filters. These filters can be designed to optimally respond to a particular type of feature by maximizing sever...
