Abstract
In this paper an improved, macroblock (MB) level, visual saliency algorithm, aimed at video compression, is presented. A Relevance Vector Machine (RVM) is trained over 3 dimensional feature vectors, pertaining to global, local and rarity measures of conspicuity, to yield probabalistic values which form the saliency map. These saliency values are used for non-uniform bit-allocation over video frames. A video compression architecture for propagation of saliency values, saving tremendous amount of computation, is also proposed.

A Newly Developed Ground Truth Dataset for Visual Saliency in Videos

TL;DR: It is evident from results that multiple kernel learning and spectral residual-based saliency algorithms perform best for different genres and motion-type videos in terms of F-measure and execution time, respectively.

Applications of Saliency Models

TL;DR: This chapter proposes a taxonomy to classify the real-life applications which can benefit from the use of attention models, and uses saliency maps to detect the regions which are the less interesting in an image.

Human Attention Modelization and Data Reduction

TL;DR: The main purpose of the attentional process is to make best use of the parallel processing resources of the authors' brains to identify as quickly as possible those parts of their environment that are key to their survival.

A model of saliency-based visual attention for rapid scene analysis

TL;DR: In this article, a visual attention system inspired by the behavior and the neuronal architecture of the early primate visual system is presented, where multiscale image features are combined into a single topographical saliency map.

A model of saliency-based visual attention for rapid scene analysis

TL;DR: A visual attention system, inspired by the behavior and the neuronal architecture of the early primate visual system, is presented, which breaks down the complex problem of scene understanding by rapidly selecting conspicuous locations to be analyzed in detail.

Graph-Based Visual Saliency

TL;DR: A new bottom-up visual saliency model, Graph-Based Visual Saliency (GBVS), is proposed, which powerfully predicts human fixations on 749 variations of 108 natural images, achieving 98% of the ROC area of a human-based control, whereas the classical algorithms of Itti & Koch achieve only 84%.

Saliency Detection: A Spectral Residual Approach

TL;DR: A simple method for the visual saliency detection is presented, independent of features, categories, or other forms of prior knowledge of the objects, and a fast method to construct the corresponding saliency map in spatial domain is proposed.

Saliency Based on Information Maximization

TL;DR: A model of bottom-up overt attention is proposed based on the principle of maximizing information sampled from a scene and is achieved in a neural circuit, which is demonstrated as having close ties with the circuitry existent in die primate visual cortex.
