/** @defgroup saliency Saliency API

Many computer vision applications may benefit from understanding where humans focus given a scene.
Other than cognitively understanding the way human perceive images and scenes, finding salient
regions and objects in the images helps various tasks such as speeding up object detection, object
recognition, object tracking and content-aware image editing.

About the saliency, there is a rich literature but the development is very fragmented. The principal
purpose of this API is to give a unique interface, a unique framework for use and plug sever
saliency algorithms, also with very different nature and methodology, but they share the same
purpose, organizing algorithms into three main categories:

**Static Saliency**: algorithms belonging to this category, exploit different image features that
allow to detect salient objects in a non dynamic scenarios.

**Motion Saliency**: algorithms belonging to this category, are particularly focused to detect
salient objects over time (hence also over frame), then there is a temporal component sealing
cosider that allows to detect "moving" objects as salient, meaning therefore also the more general
sense of detection the changes in the scene.

**Objectness**: Objectness is usually represented as a value which reflects how likely an image
window covers an object of any category. Algorithms belonging to this category, avoid making
decisions early on, by proposing a small number of category-independent proposals, that are expected
to cover all objects in an image. Being able to perceive objects before identifying them is closely
related to bottom up visual attention (saliency).
