N2 - In this paper we propose a low-complexity face recognition system based on the Walsh-Hadamard transform. This system can be easily implemented on a fixed point processor and offers a good compromise between computational burden and identification rates. We have evaluated that with 169 integer coefficients per face we achieve better results (92%) than the classical eigenfaces approach (86.5%), and close to the DCT (92.5%) with a reduced computational cost.
