Different organisms perceives & process things differently; bats use ultrasound to navigate through their way, frog uses different contours, and so we human also have developed a visual system. The output of the signals sent by retina is transformed and processed by a Human Brain which is the most complex system ever studied.
Since, the time antediluvian, brain has been the centre of interest. It is the system that every civilization tried to study, whether it be Indians or Europeans, all have put up their best efforts to study the brain in their own styles which resulted to form different interpretations.
Brain processes data to information to form a perception; the factors affecting the latter are Beliefs (or rather environmental factors) and stimulus which is the agent. The agent is the sensory organ which transmits the data to the brain. Now, this could be any sense organ like nose, tongue, touch, visual system etc.
Among these, the most fascinating is visual system, not because it is the most powerful and mostly used sensory organ but, it has an intelligence system of its own. Right from the time of birth, baby tries to learn and adapt himself to the things he percives through the channel of eye to eventually become a virtuso visionary. Throughout his initial stages of life he trains himself to be able to recognise and predict the 3-D objects with ultimate perfection.
The things we see(i.e the focus of eyes) are not as simple as we think they are and, the things we don’t see (i.e observing via unconsious root or background) also has a major role in generating one’s perception. So the process of vision is a very complex, amalgaming both the concious and unconcious viewing. The notion has been proved experimentally that if you remove the background scene from any movie then, people generally confuse the context of the scene. Also there has been studies where the unconcious viewing has also played a major role.
If we consider only the processing of visual stimulus, the brain consists of two processing pathways: Dorsal (where) pathway and Ventral (what) pathway. In addition to this amygdala is also present which stores unconsious and emotional memories of the past, this is key player in determining the action after visual stimuli. Studies also proved the functioning of V3 and V4 part of the brain. If in an individual V4 stops functioning then his “what” pathway is blocked and so inspite of not seeing the object, he can perfectly judge the shape and orientation of the object.

Also the visual processing is done in multistep and is buffered for a specific period of time. One can see the motion in the flashing light which is flashed synchronistically within a particular threshold time limit. Not only this, human visual system also expects changes in the same fashion as before i.e synchronisically.
