The instructor runs the images through the Itti-Koch saliency algorithm, which marks pixels that ought to jump out at viewers because they represent regions that are different from their surroundings. text/html 2019-09-21T18:45:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.anthonycate.org/doku.php?id=teaching:saliency:saliency_instructions&rev=1569091543&do=diff BACKGROUND A recentadvance in the study of visual attention has been the development of computer algorithms for automatic detection of visual salience in images. These algorithms typically work by detecting the presence of basic-level visual features of the human visual system (e.g. edge orientation, brightness and color) and then identifying spatial regions that hold singleton features.
