Abstract

Visual attention significantly affects how we perceive 3D environments and saliency is a part of visual attention expressing how likely a scene or item is to capture our attention due to its apparent features. Saliency relies upon geometry, shading, size, and other visual attributes of items. Illumination of a scene has an important impact on those visual properties; therefore, it influences the saliency distribution of a visual field. In this paper, the saliency of objects will be recognized by different light location. This work aims to control the saliency by controlling the illumination parameters in a 3D scene. For this reason, we created a sensible 3D scene, and the light position that gets maximum saliency of point of interest objects are investigated. In this work, 2D renderings that are from environmental viewpoints are considered and results are compared according to saliency distribution with different light positions. Also, for this process, different saliency methods and calculations are used to get successful results and eye tracker testing is used to compare the results.
