===Ray Saliency: Bottom-Up Saliency for a Rotating and Zooming Camera===
Speaker: [http://garrettwarnell.com/ Garrett Warnell] -- Date: October 17, 2013

We extend the classical notion of visual saliency to multi-image data collected using a stationary pan-tilt-zoom (PTZ) camera. We show why existing saliency methods are not effective for this type of data, and propose ray saliency: a modified notion of visual saliency that utilizes knowledge of the imaging process in order to appropriately incorporate the context provided by multiple images. We present a practical, mosaic-free method by which to quantify and calculate ray saliency, and demonstrate its usefulness on PTZ imagery.
