Saliency Map Computation

摘要

Saliency map computation is described. In one or more implementations, a base saliency map is generated for an image of a scene. The base saliency map may be generated from intermediate saliency maps computed for boundary regions of the image. Each of the intermediate saliency maps may represent visual saliency of portions of the scene that are captured in the corresponding boundary region. The boundary regions may include, for instance, a top boundary region, a bottom boundary region, a left boundary region, and a right boundary region. Further, the intermediate saliency maps may be combined in such a way that an effect of a foreground object on the saliency map is suppressed. The foreground objects for which the effect is suppressed are those that occupy a majority of one of the boundary regions.

1. A method implemented by a computing device, the method comprising:
determining boundary regions of an image that depicts a scene, each of the boundary regions comprising less than an entirety of the image; computing intermediate saliency maps of each of the boundary regions, the intermediate saliency maps representing visual saliency of portions of the scene that are captured in the boundary regions, the intermediate saliency maps computed based on the visual saliency of the portions of the scene captured in the boundary regions being background of the scene; and combining the intermediate saliency maps to generate a base saliency map of the image, the intermediate saliency maps being combined to suppress an effect of one or more foreground objects on the base saliency map, the one or more foreground objects that have the effect suppressed occupying a majority of one of the boundary regions.
