Abstract: A system may access an image that is captured by an imaging device and that depicts an operational scene illuminated by close-range light. The system may also access a depth map of the operational scene. Based on the image and the depth map, the system may generate a processed image depicting the operational scene as being illuminated by a virtual light source that is to be simulated to be illuminating the operational scene and may provide the processed image for presentation on a display screen. Corresponding systems and methods are also disclosed.

Abstract: An electronic communication system is controlled by a content service provider to return relevant information from a content specific database in response to a user query. The content service provider compiles a plurality of content specific databases, each dedicated to a category of information of interest to the user. The user registers a user profile with the content service provider. A query, including the selected content specific database, is transmitted from the user to the content service provider. The selected content specific database is searched for the first level query within context of the user profile. A menu of matches is generated from the content specific database for the first level query. The menu is organized by relevance scores assigned to the matches based on correspondence to the first level query. The menu is transmitted from the content service provider through the electronic communication network to the user.
