Visual Saliency Detection REU Student: LaTia Jefferson Graduate Student: Nasim Souly

Visual Salience Definition Background research Importance Human visual system General saliency Orientation (scanning process) Bottom-up versus top-down Importance Decreasing the amount of information to process

Articles Incremental Sparse Saliency Detection Yin Li ICIP 2009 Visual Saliency Detection via Sparsity Pursuit Junchi Yan IEFE 2010 Visual Attention Detection in Video Sequences Using Spatiotemporal Cues Yun Zhai, Dr. Muarak Shah, UCF

Current Research Questions How to represent 3-dimensional saliency from film or video clips? How does the HVS model saliency in video? What are the key parts of attention in video?

Next Steps Coding in Matlab Read relevant articles Starting to vectorize patches and find filters/features for the cuboids Using the sparse representation package OMP Box Read relevant articles Psychology of video salience Calculating salience in other ways
