A Perceptual Evaluation of the StyleGAN2-ADA Generated Images of Translucent Objects. We validate our derivatives by comparing against finite differences and demonstrate the effectiveness of our technique by comparing inverse-rendering performance with previous methods. ![]() Such rules are likely candidates for models of human visual perception of wrinkles in human skin or articulations of cumulus clouds. Vision Sciences Society Annual Meeting Abstract December 2022. We show how to develop rules of thumb for generic cases. ![]() In more general cases one needs to make certain approximations. In simple cases the scattering problem can be solved and we obtain models of 'shading' of translucent material that are distinct from the opaque Lambertian case. We study the optical properties for a number of geometries. A general theory of 'shading' in the case of translucent objects is not available. A material or object that is perfectly clear in its appearance is known as a transparent material such as ordinary glass. In the limit of very strong scattering these materials approach opaque Lambertian surfaces, in the limit of very weak scattering they approach transparent objects such as glass or water. In such cases there can be no 'shading' proper. What Is Transparent Object The word transparent is used to refer to something that is see-through or clear. In cases of translucent objects photons penetrate the surface and enter the volume of the object, perhaps to re-emerge from the surface at another location. Most objects are opaque and include things made of wood, stone, and metal. A translucent material allows light to pass through, but prevents the light from forming images. If an object does not allow any light to pass through it then it is opaque. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper. ![]() Many objects are not at all opaque though. Examples of transparent items are glass, water, and air. Theories of 'shape from shading' assume that the shading is due to collimated beams irradiating opaque smooth Lambertian surface. ![]()
