Artificial Intelligence (AI) is an exciting and fascinating research area in computer science emerging to develop machines with human intelligence or human behaviour. One of the goals in AI is to develop algorithms and techniques based on the study of pinnacle of intelligence, human brain. The new direction makes a breakthrough in AI while facilitating powerful clues to the neuroscience to understand the unrevealed mechanisms in human brain. The traditional means of manipulating visual inputs by artificial systems are highly dependent on human intervention. A study of human vision system can be considered as a promising direction towards achieving truly intelligent artificial vision system. In this thesis, the main contribution is to inves...
