The relevance of low and high spatial-frequency information for the recognition of photographs of faces has been investigated by testing recognition of faces that have been either low-pass (LP) or high-pass (HP) filtered in the spatial-frequency domain. The highest resolvable spatial frequency was set at 15 cycles per face width (cycles fw(-1)). Recognition was much less accurate for images that contained only the low spatial frequencies (up to 5 cycles fw(-1)) than for images that contained only spatial frequencies higher than 5 cycles fw(-1).
