Objects and Scenes Flashcards
Conceptual system
other (d) systems: “meaning”,
integration with other types of knowledge, memory
Visual cognition:
object, face, scene representations
Low-level computations
integration between different types of representations
Detectors:
different subsystems working in parallel
Recognition of an object can occur in
about 100 milliseconds (one tenth of a second)
Categorization can take place in about
150 milliseconds
Natural object categorization Early peak at:
about 75 ms: visual recognition
Natural object categorization late peak at about:
150 ms: category decision
Recognition should be, to a large extent
view- point invariant: Objects should be recognized fast independent of point of view
Recognition occurs fast under noisy conditions:
occlusion, low luminance, different shapes*
he task of intermediate and higher levels:
To build 3-D representations from 2-D retinotopic
representation
