A theory of illusory transparency and lightness is described for monocular and binocular images containing X-, T- and I-contour junctions. This theory asserts that the geometric and luminance relationships of contour junctions induce illusory transparency and lightness percepts by causing a phenomenal scission of a homogenous luminance into multiple contributions. Specifically, it is argued that a discontinuous change in contrast along aligned contours that preserve contrast polarity induces a… 
Lines That Induce Phenomenal Transparency
TLDR
The transparency phenomena (‘transparency of the contoured surface’) perceived in this context conform to the constraints of Metelli's model, as demonstrated by a second experiment, designed to gather ‘opacity’ ratings of stimuli.
Lightness and Perceptual Transparency
TLDR
It is suggested that mid-level and higher-level factors, such as image junction structure and perceived illumination and transparency, are ineffective for generating strong lightness illusions on their own, and that these factors are not ‘stronger’ than luminance contrast in determining lightness.
The role of occlusion in the perception of depth, lightness, and opacity.

TLDR
A theory is presented that explains how the visual system infers the lightness, opacity, and depth of surfaces from stereoscopic images and suggests that a global transmittance anchoring principle expresses how variations in contrast magnitudes are used to infer the presence of transparent surfaces.
Lightness from contrast: A selective integration model
TLDR
The selective integration model (SIM) extends the explanatory power of previous models, allowing simulation of a number of phenomena, including White’s effect, the Benary Cross, and shading and transparency effects reported by Adelson (1993), as well as aspects of motion, depth, haploscopiC.
Image segmentation and lightness perception
TLDR
New lightness illusions are presented that unequivocally demonstrate the effect that layered image representations can have in lightness perception and indicate that mechanisms involved in decomposing images into layered representations can play a decisive role in the perception of surface lightness.
Stereoscopic Surface Perception these interocular positional shifts and discovering how
these local signals are integrated into a coherent representation of surface structure. Here, a series of novel stereoscopic phenomena are presented that demonstrate a striking dissociation between
The role of scission in the perception of color and opacity.
TLDR
It is shown that the chromatic contrast relationships along contours play a critical role in determining when chromatic scission occurs and in determining the perceived color and opacity of the layers that emerge when such conditions prevail.
Brightness/darkness induction and the genesis of a contour

TLDR
It is demonstrated that the appearance in the perceptual field of this integrated unit, or contour of invariant CP, is concomitant with a vivid brightness alteration of the surfaces at its opposite sides.
Testing the role of luminance edges in White's illusion with contour adaptation.
TLDR
A temporal adaptation mechanism is implemented in three spatial filtering models of lightness perception and it is concluded that White's illusion is largely determined by edge contrast across the edge orthogonal to the grating, whereas the parallel edge has little or no influence.
The role of image blur
In constructing the percept of transparency, the visual system must decompose the light intensity at each image location into two componentsöone for the partially transmissive surface, the other for

A THEORETICAL ANALYSIS OF ILLUSORY CONTOUR FORMATION IN STEREOPSIS
A theoretical analysis of how illusory contours are formed in untextured stereograms is presented. This analysis focuses on the role of contour junctions in initiating surface interpolation
The role of partial occlusion in stereopsis
MODELS of stereopsis typically assume that all the information about stereoscopic depth is contained in the disparity field, that is, the positional differences of image features that arise from
Transparency: Relation to Depth, Subjective Contours, Luminance, and Neon Color Spreading
TLDR
Perceived transparency is interpreted as much a ‘cause’, as an ‘effect’ and is shown that transparency is not coupled strongly to real-world chromatic constraints since combinations of luminance and color which would be unlikely to arise in real- world scenes still give rise to the perception of transparency.

TLDR
Day and Jory (1980) and Day and Kasperczyk (1983a, 1983b) have proposed that illusory contours, apparent edges in physically uniform regions, are due primarily to the spread of induced contrast to partially delineated borders.

A theory of visual interpolation in object perception
TLDR
A new theory explaining the perception of partly occluded objects and illusory figures, from both static and kinematic information, in a unified framework is described, with a detailed theory of unit formation that accounts for most cases of boundary perception in the absence of local physical specification.
Second-order illusions: Mach bands, chevreul, and Craik-O'Brien-Cornsweet
TLDR
The results indicate that second-order (texture) illusions result from fullwave, not halfwave, rectification and involve spatial interactions that are remarkably similar to those in first- order (luminance) processing.
Shape from shadows.
TLDR
The results suggest that the interpretation of shadows begins with the identification of acceptable shadow borders by a cooperative process that requires consistent contrast polarity across a range of scales at each point along the border.
The perception of transparency with achromatic colors
TLDR
The results are discussed in terms of how the pattern of intensities relates to other stimulus information, such as figural configuration, in producing the perception of transparency.
The relation between color spreading and illusory contours
TLDR
The remarkable overlap of the two curves for the likelihood of perceiving illusory contours in the Ehrenstein figure and in the Redies-Spillmann figure suggests that the illusories surrounding brightness enhancement and those surrounding neon color spreading are caused by the same mechanism.
