Experiments in Texture Perception
Abstract
Over the past year, our special graphics display has been used to examine several properties of texture perception. The most important result is the finding that most uniform textures can be simulated or 'matched' by a very small number of variables, provided that these variables contain the basic elemental tokens of the display. The number of these matching variables may be as small as three, and usually four is sufficient to produce excellent 'texture metamers'. Both linear, or one-dimensional luminance distributions and two- dimensional texture patterns are being studied. Additional work has also been completed that examined the discriminibility of different n-gram statistics for random-check textures. However, this approach does not appear to be so fruitful a method for studying texture perception as the method of 'Generalized Colorimetry', which is outlined briefly in the first section of this report. Our work to date indicates that the human observer is quite poor at discriminating textures. Hence a considerable saving in communicating texture information can be achieved through the use of texture metamers.
