摘要

The perception of transparency in human's build environment constitutes a significant cognitive challenge, also affecting the user's safety. It is supposed that, apart from the mid-level vision transparency cues, specular reflection is also a key feature of the perceived image taken into consideration by the visual system. In the paper, this optical phenomenon was observed and estimated based on the author's own method, here called the "pictorial image analysis", which uses pairs of photographs: unmodified - showing the virtual image on the building's transparent facade, and modified - devoid of this image. The images were digitally processed to extract the reflection laid over the undisturbed transmitted image. The results show that evident specular reflection significantly improves the perception of transparent surfaces, but, in the case of excess or back-lit panes, it can hardly be used as perceptual cue.
