Humans perceive shape rapidly and effortlessly but have great difficulties describing what they perceive. This suggests that the representation of shape in the brain is abstract and very unlike that used in conscious thought. Here we explore the prop

The sensory pathways of animals are well adapted to processing a special class of signals, namely stimuli from the animal's environment. An important fact about natural stimuli is that they are typically very redundant and hence the sampled represent

A recent computational theory suggests that visual processing in the retina and the lateral geniculate nucleus (LGN) serves to recode information into an efficient form (Atick and Redlich, 1990). Information theoretic analysis showed that the represe

Low-dimensional representations of sensory signals are key to solving many of the computational problems encountered in high-level vision. Principal component analysis (PCA) has been used in the pa...

Natural time-varying images possess substantial spatiotemporal correlations. We measure these correlations-or equivalently the power spectrum-for an ensemble of more than a thousand segments of motion pictures and we find significant regularities. Mo

Natural time-varying images possess significant temporal correlations when sampled frame by frame by the photoreceptors. These correlations persist even after retinal processing and hence, under natural activation conditions, the signal sent to the l

Stereo images are highly redundant; the left and right frames of typical scenes are very similar. We explore the consequences of the hypothesis that cortical cells—in addition to their multiscale coding strategies—are concerned with reducing bino

We explore the hypothesis that linear cortical neurons are concerned with building a particular type of representation of the visual world—one that not only preserves the information and the efficiency achieved by the retina, but in addition preser

An unsupervised developmental algorithm for linear maps is derived which reduces the pixel-entropy (using the measure introduced in previous work) at every update and thus removes pairwise correlations between pixels. Since the measure of pixel-entro
