abstract = {Using artistic methods for manipulating perception as a basis, we
present a technique that creates facial images with conflicting
emotional states at different spatial frequencies. The foveal and
peripheral components of the human visual system tend to interpret
the emotional state of the subject differently, adding a degree of
elusiveness to facial image. The system first isolates the coarser
low spatial frequency components and finer high spatial frequency
details from two images with differing facial expressions. Our
technique then performs image segmentation with edge detection,
and morphs the images. In practice we have found that high spatial
frequency elements determine the dominant expression in the
resulting image, while the low spatial frequency elements
contribute subtlety.},
