[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.
Color constancy: The colors of a hot air balloon are recognized as being the same in sun and shade. Example of the Land effect. Color constancy makes the above image appear to have red, green and blue hues, especially if it is the only light source in a dark room, even though it is composed of only light and dark shades of red and white.
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 ...
An example of a multiview orthographic drawing from a US Patent (1913), showing two views of the same object. Third angle projection is used. In third-angle projection , the object is conceptually located in quadrant III, i.e. it is positioned below and behind the viewing planes, the planes are transparent , and each view is pulled onto the ...

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 ]
