The SaliencyToolbox is a collection of Matlab functions and scripts for computing the saliency map for an image, for determining the extent of a proto-object, and for serially scanning the image with the focus of attention. It has been cited in more than 500 papers.
The SaliencyToolbox is in part a reimplementation of the iNVT toolkit at Laurent Itti's lab at the USC. This toolbox complements the iNVT code in that it is more compact (about 5,000 versus 360,000 lines of code) and easier to understand and experiment with, but it only contains the core functionality for attending to salient image regions.
Because the toolbox is entirely implemented in Matlab, processing an image with the SaliencyToolbox in Matlab takes longer than with the iNVT code. Whenever processing speed or feature richness is paramount, the iNVT code should be preferred. For computing the saliency map or attending to salient proto-objects in an image in a transparent and platform independent way, the SaliencyToolbox is a good choice.
