/** @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).
