Visual attention has a major impact on how we perceive 3D environments and saliency is a component of visual attention expressing how likely a scene or item is to capture our attention due to its apparent features. Saliency relies upon shape, shading, brightness, and other visual attributes of items. The saliency distribution of a visual field is influenced by the illumination of a scene, which has a significant impact on those visual properties. This work aims to control the saliency by manipulating the illumination parameters in a 3D scene. For this reason, given a sensible 3D scene, the light parameters that provide maximum saliency for the point of interest objects are investigated. In other words, we propose a method for task-aware automatic lighting setup. In this paper, 2D renderings of a 3D scene from various perspectives are considered, and the effects are analyzed in terms of saliency distribution under various lighting conditions. Also, for this process, different saliency estimation methods and calculations are investigated and eye tracker based user experiments are conducted to verify the results.
