Through the investigation of brain and the area that receives , stores and processes visual information, and also by the emotions which are generated by this process, we can investigate the effect of visual detection, organization and coding of images surround us in our lives.                                                                                                                                                                                                                    

The images are relevant to our mental education, for example the way we see and perceive the environment and the way we are associated with it. Images turn in familiar symbols, and affect us, even subconsciously. Many researchers in artificial intelligence and cognitive psychology, such as physicists, neuroscientists ,neurobiologists, philosophers  and artists,  each one from a different perspective, studies human vision and cognition, more or less, at similar conclusions. So by the use of special techniques, they explore combined sections such as brain and psychology, through the active process of vision.                                                                          

Reports from theories of ancient and modern philosophers, artists and psychologists, along with scientific studies of the visual side of  brain, helping us to understand better the impact of images in our lives. It’ s also known that pictures of every kind of art  are used in studies of neurobiology and visual perception.                                                                                                                                         

The world is not what we see, hear, smell, and there are many phenomena we can’t perceive. Our vision is incomplete or under some circumstances completely neutralized, because of invisible elements, such as infrared radiation. Additionally, the color, the background, the presence of other objects, the involvement of other senses and memory affect our visual perception. So we usually have a false sense of ''reality''. This inability of the eye we call mirage. Through the illusions it’s proved that the mechanisms of vision which confirms that our perception is complicated and have a vast dark side.
