You need something in your long-term memory to be activated by a stimulus that allows you to take an input stimulus and associate it with something stored in memory. Essentially, look at object, search for features (motion, color, form) edge group it (surface extraction). View normalization Then look for stored descriptions in long term memory. Hypothesis 1 for memory: Stored templates: the prototypical shape, what you see from your one vantage point. Recognition: match the stimulus representation to the stored template Problems: example with the anteater. variability: what happens when you see object in non prototypical state? Hypothesis 2 : 3-D, object centered structural decisions. Not how you happen to see it, but rather on how the object is structured: has to do with objects own geometry. We store and categorize the 3-D geometry. Representation that has the essentials for recognition Containing features that…. Based on principal axes of elongation and symmetry Major features represented relative to these axis, not the outside world. Orientation invariant 3d view of normalization Critical step to derive a structural description from an image View normalization 1 identify the major axes of symmetry of elongation of the object itself. Rather than from the viewpoint of the viewer
