Saliency Detection
Image pyramid based saliency map Create image pyramid: blur and shrink the
image Build the image differences Add the image differences

Spatio-temporal Saliency Histograms
Spatiotemporal saliency model Split image into grid cells (cell size: e.g. 20x20 pixels for HD) Compute histogram of pyramid differences for each cell Compare histograms
Current histogram vs. average of histograms from past second Distance function: earth mover distance
Region of interest (ROI) Convert high salient regions into rectangles
Application: automatic view selection
