Human vision: saccades and fixations

Human vision explores an image by fixations in some specific regions and fast movements or saccades from one region to another. Long saccades are, in general, less frequent. Depending on the task to be performed and depending on the image complexity, as we found in [Bonev, Chuang, Escolano 2012], the need for a long saccade may vary.
In the following slow-motion video we show an example of the behaviour of human saccades.
