Subjective constancy or perceptual constancy is the perception of an object or quality as constant even though our sensation of the object changes. [1] While the physical characteristics of an object may not change, in an attempt to deal with the external world, the human perceptual system has mechanisms that adjust to the stimulus.
[2]: 518 The microbiologist examines the appearance of the colony, noting specific features such as size, colour, shape, consistency, and opacity. [1]: 165–8 A hand lens or magnifying glass may be used to view colonies in greater detail. [3]: 96 The opacity of a microbial colony can be described as transparent, translucent, or opaque.
In computer vision, photo-consistency determines whether a given voxel is occupied. A voxel is considered to be photo consistent when its color appears to be similar to all the cameras that can see it. [ 1 ]
Form perception is the recognition of visual elements of objects, specifically those to do with shapes, patterns and previously identified important characteristics. An object is perceived by the retina as a two-dimensional image, [1] but the image can vary for the same object in terms of the context with which it is viewed, the apparent size of the object, the angle from which it is viewed ...
Accidental viewpoint contributes to the successful perception of anamorphic images, which intentionally appear distorted from non-accidental viewpoints. Other than viewing the image from a specific location, the distortion can be countered by looking at the image when reflected in a mirror (known as catoptric anamorphoses [ 9 ] ).

Ehrenstein also found when he reduced the size of the overall figure, it enhanced the paradox and made the contour appear thicker. The shapes in the image remain constant despite small changes in the overall characteristics of the configuration. The monochrome colours of the images further enhances the illusion of the square becoming curved. [7]
