... that males and females exhibit differences in the extent to which ommatidia are aligned. Both the number of misaligned ommatidia suitable for robust polarization detection and the number of aligned ommatidia suitable for edge detection vary with respect to both sex and eye patch elevation. Thus, J. evagoras...

...Cedric P. van den Berg; John A. Endler; Daniel E. J. Papinczak; Karen L. Cheney ABSTRACT Edge detection is important for object detection and recognition. However, we do not know whether edge statistics accurately predict the detection of prey by potential predators. This is crucial given...

...Yanqiong Zhou; Xiaoxiao Ji; Haiyun Gong; Zhefeng Gong; Li Liu SUMMARY Edges represent important information in object recognition, and thus edge detection is crucial for animal survival. Various types of edges result from visual contrast, such as luminance contrast and color contrast. So far...

.... Why was the scanning behaviour absent in the edge detection task? One reason could be that in the latter the patterns were presented on a horizontal plane (see Fig. 4 ), whereas in the pattern discrimination experiments they were placed on a vertical plane ( Fig. 6 ). Differences in visual...
