....to ensure thorough scanning of the image, and prevented cycling through only a limited number of locations. All parameters are fixed in our implementation [17] and the system proved stable in time for all images studied. C. Comparison with spatial frequency content models Reinagel and Zador [18] recently used an eye tracking device to analyze the local spatial frequency distributions along eye scan paths generated by humans while free viewing grayscale images. They found the spatial frequency content at the fixated locations to be significantly higher than, on average, at random ....

....on which locations are the most salient. However, in all images studied, most attended locations were objects of interest, such as faces, flags, persons, buildings or vehicles. Model predictions were compared to the measure of local SFC, in an experiment similar to that of Reinagel and Zador [18], using natural scenes with salient traffic signs (90 images) red soda can (104 images) or vehicle s emergency triangle (64 images) Similar to Reinagel and Zador s findings, the SFC at attended locations was significantly higher than the average SFC, by a factor decreasing from 2:5 Sigma 0:05 ....
