Abstract
We study the spatiotemporal correlation in natural time-varying
images and explore the hypothesis that the visual system is concerned
with the optimal coding of visual representation through
spatiotemporal decorrelation of the input signal. Based on the
measured spatiotemporal power spectrum, the transform needed to
decorrelate input signal is derived analytically and then compared
with the actual processing observed in psychophysical experiments.
