Visual fields in ostriches
Article Abstract:
The binocular field of ostriches, whose eyes are the largest among all land vertebrates is very small. Visual control of bill position during highly accurate pecks are used by ostriches foraging for food, with the foraging behavior primarily determining binocular field properties. Other birds that differ in eye size and eye separation and in their ecology and phylogeny also exhibit similar narrow frontal binocular fields.

Hierarchy and adaptivity in segmenting visual scenes
Article Abstract:
A new, highly efficient approach that determines all salient regions of an image and builds them into a hierarchical structure is described. The aggregates of various sizes are revealed as salient, without predetermining their number or scale and the results using the algorithm, segmentation by weighted aggregation, are found to be more accurate and significantly faster than previous approaches.

Postsaccadic visual references generate presaccadic compression of space
Article Abstract:
The brain may use an extraretinal eye position signal to compensate for gaze changes or may use the image to determine associated locations. The dependence of perisaccadic mislocalization on available visual spatial references at certain times around a saccade has been determined. Presaccadic compression is found to arise only if visual references are available after the saccade.
