The Retinal image can vary for the same object in terms of the context with which it is viewed, the apparent size of the object, the angle from which it is viewed, how illuminated it is, as well as where it resides in our field of vision. It is remarkable that despite the fact that each instance of observing the same object leads to a unique retinal response pattern, the visual processing that takes place in our brain is capable of recognizing these experiences as analogous in a way that allows for invariant object recognition. Through visual processing in the temporal, parietal and occipital lobe these retinal images are converted into a 3D image. Visual processing occurs in a hierarchy with the lowest levels recognizing lines and contours, and slightly higher levels performing tasks such as completing boundaries...
