Abstract

In this brief, one-dimensional (1-D) and two-dimensional (2D) fast algorithms for realizing the center weighted Hadamard transform (CWHT) are proposed. Based on the Kronecker product and direct sum operations, the proposed 1-D and 2-D CWHT algorithms through matrix decompositions require fewer computations than the existing methods. With low complexity and regular modularity, the proposed algorithms are suitable for VLSI implementation to achieve real-time signal processing and compression.
