Architectural Impression on Illumination

Improved Illumination Estimation for Photon Maps in Architectural Scenes

The photon map algorithm provides a number of advantages for fast global illumination algorithms. In order to calculate the illumination at each point in a scene, the photon density needs to be estimated. Standard estimation methods will have problems with typical architectural scenes, as walls and corners will lead to undesirable light and shadow leaks. We introduce a new method for estimating...

Perception of Lightness and Brightness of Achromatic Surface Color and Impression of Illumination

The relationships between lightness and brightness responses under the condition that achromatic "surface color " appears and the relationships between perceived illumination and brightness were examined. The Ss were required to make categorical judgments upon both lightness and brightness of the test patches presented on black and white backgrounds and upon the over-all illumination in the vis...

Politician's Strategic Impression Management on Instagram

With the growing trend of Instagram usage among politicians, this study investigates the effects of two self-presentation styles of personalization (i.e. presenting the private over the public life of a politician) and interactivity (i.e. presenting the active versus passive voice of a politician) on voters’ perception of politicians and their voting intention in the context of Instagram. The r...
