As manufacturers adapt to the needs of today's buyers' market, which is replacing the manufacturers' market of yesterday, the need for product variety will increase. Even today, manufacturers of products which are built to customer order, for example

In theory, global shading may help with the estimation of local surface structurefrom shading (e.g., in specifying the illuminant direction). Empirically, we do not know whether human observers combine the information given by the local and global sh

Theoretically, metric solid shape is not determined uniquely by shading. Consequently, human vision has difficulty in categorizing shape when shading is the only cue. In the present research, subjects were required to categorize shaded quadric surfac

We report on the extent to which human observers are able to indicate the gradient direction of a luminance ramp. In our experiment modulation depth ranged from 1 to 64% and field sizes subtended 0.5 to 47.5 degrees of visual angle. Observers are not

The perception of surface relief from random shading patterns is measured by having observers adjust three-dimensional local probes, the projections of which are superimposed on the image. Three observers perform four settings of 91 probes on each of
