PCS 2015 Special Session 1

Visual Attention Modelling and its Applications in Visual Signal Processing

Humans are the ultimate consumers of the majority of (if not all) processed visual signals, and as a result of evolution, the human visual system (HVS) has developed a selective attention mechanism to focus on salient regions in visual signals. Therefore, it would be beneficial to use saliency based criteria in design, implementation and optimization of visual and multimedia processing systems.

This special session therefore seeks submissions that advance knowledge and represent the latest technology developments in the area of saliency-based visual signal modelling and processing (especially visual signal coding). Apart from the processing for traditional visual data, we are particularly interested in emerging new types of visual data such as 3D visual data, high dynamic range (HDR) imagery, high-definition television (HDTV), etc.

Topics of interest for this special session therefore include, but are not limited to:

  • Computational models of visual attention
  • Saliency based quality metrics for visual signals
  • Saliency based applications in image coding, video coding, retargeting, 3D signal processing, etc.
  • In-depth analysis of attention-based visual signal processing systems
  • Subjective evaluation methodology for new media, such as HDR/3D/multiview/free-view video
  • Visual attention model validation
  • Pre- and post- processing techniques to enhance viewing experience
  • User-oriented streaming, adaptation and retargeting
  • Applications and databases related to attention-based visual processing
