Abstract
This work addresses the design of a novel complex steerable wavelet construction and its implementation on reconfigurable logic. The wavelet decomposition uses pairs of bandpass filters that display symmetry and antisymmetry about a steerable axis of orientation. The design is targeted for implementation in hardware, thus one of the desired properties is the small number of unique kernels. A detailed description of the implementation of the design in hardware is given. Moreover, results regarding the speed of our design compared to a software implementation, and the error in the filter responses due to fixed point representation, are reported. To show the applicability of the design to real life situations, a corner detection algorithm is illustrated.
