Effect of scene dimensionality on colour constancy with real three-dimensional scenes and objects.
The effect of scene dimensionality on colour constancy was tested with real scenes and objects. Observers viewed a three-dimensional (3-D) scene, or its two-dimensional (2-D) planar projection, through a large beam-splitter that projected the virtual image of a real test object (a cube or its 2-D projection) so that it appeared part of the scene. Test object and scene could be illuminated indep...
متن کاملEffect of scene complexity on colour constancy with real three-dimensional scenes and objects.
The effect of scene complexity on colour constancy was tested with a novel technique in which a virtual image of a real 3-D test object was projected into a real 3-D scene. Observers made discriminations between illuminant and material changes in simple and complex scenes. The extent of colour constancy achieved varied little with either scene structure or test-object colour, suggesting a domin...
متن کاملMethods For Analyzing Three Dimensional Scenes
Several methods f o r analyzing three dimensional scenes are discussed w i t h respect to t h e i r advantages and d i f f i c u l t i e s i n g e t t i n g r e a l three d i mensional coordinates. Stereo p i c t u r e processing and l i g h t i n t e r s e c t i n g methods are described along w i t h the r e s u l t of a new hardware system. On the example of a software system some special pr...
متن کاملSurface color perception in three-dimensional scenes.
Researchers studying surface color perception have typically used stimuli that consist of a small number of matte patches (real or simulated) embedded in a plane perpendicular to the line of sight (a "Mondrian," Land & McCann, 1971). Reliable estimation of the color of a matte surface is a difficult if not impossible computational problem in such limited scenes (Maloney, 1999). In more realisti...
متن کاملVisibility in three-dimensional cluttered scenes.
Three-dimensional (3D) cluttered scenes consist of a large number of small surfaces distributed randomly in a 3D view volume. The canonical example is the foliage of a tree or bush. 3D cluttered scenes are challenging for vision tasks such as object recognition and depth perception because most surfaces or objects are only partly visible. This paper examines the probabilities of surface visibil...
