In summary, the theory of topological perception has brought a significant challenge to the traditional model of visual perception. Chen's theoretical formulation and experimental evidence forces us to consider the importance of invariance extraction in visual perception. In this regard, it is difficult to over-estimate the contribution of the topological perception theory to our eventual understanding of vision. However, instead of contrasting "local to global" with "global to local", is it possible to consider visual perception as involving both "local to global" and "global to local" processes? Maybe the traditional hierarchical theory favouring local to global processing and Lin Chen's topological theory are not unlike the trichromatic and the opponent theories for colour vision.
