Three Demo Productions (so far)Slide6

Saliency Map

Center-surround model

inspired from biological models of human visual sensory system

Center-surround featuresPixel intensity

Color chromatic opponents RG and BY

Saliency map for still images

 Slide7

Saliency Detection

Image pyramid based saliency map

Create image pyramid: blur and shrink the image

Build the image differences

Add the image differencesSlide8

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
