The perceived orientation of a line or grating is affected by the orientation structure of the
surrounding image: the tilt illusion. Here, I offer a selective review of the literature on the tilt …

Spatial context in images induces perceptual phenomena associated with salience and
modulates the responses of neurons in primary visual cortex (V1). However, the …

The tilt illusion is a paradigmatic example of contextual influences on perception. We
analyze it in terms of a neural population model for the perceptual organization of visual …

Context is known to affect how a stimulus is perceived. A variety of illusions have been
attributed to contextual processing—from orientation tilt effects to chromatic induction …

Center-surround modulation in visual processing reflects a normalization process of contrast
gain control in the responsive neurons. Prior adaptation to a clockwise (CW) tilted grating …

In the tilt illusion, the perceived orientation of a target grating depends strongly on the
orientation of a surround. When the orientations of the center and surround gratings differ by …

The human visual system continuously adjusts to the current environment. To investigate
these adjustments, biases in observers' perceptions owing to changes in the visual …

Contextual effects abound in the real world; how we perceive an object depends on what
surrounds it. A classic example of this is the tilt illusion (TI) whereby the presence of a …

A central hypothesis about early visual processing is that it represents inputs in a coordinate
system matched to the statistics of natural scenes. Simple versions of this lead to Gabor-like …

A vertical target is perceived as tilted against a slightly tilted inducer surrounding it. To
identify the temporal resolution and temporal extent of this phenomenon of orientation …
