Object Recognition Cognitive Psychology Lecture 02 - Part 5 (Object Recognition)

Question 1

What is object recognition?

Answer 1

Object recognition is a fundamental process that serves as a gateway from vision to cognitive processes such as categorization, language and reasoning. The visual representations that allow us to recognize objects do more than merely tell us what we are looking at.

Question 2

What is the recognition by components model?

Answer 2

Recognition-by-components (RBC; Biederman, 1987) is a theory of object recognition in humans that accounts for the successful identification of objects despite changes in the size or orientation of the image

Question 3

What is marr theory?

Answer 3

Marr [Mar82] proposed three different levels for the understanding of information processing systems (having vision systems as the target example): computational theory; representation and algorithm; and hardware implementation.

Question 4

What is marr theory in details?

Answer 4

-Full primal sketch: Identification of contours and basic shapes
-Two and half dimensional sketch: Addition of depth perception
-Hierarchical organization of surface and volumetric primitives

Question 5

What are geons in psychology?

Answer 5

n. a simple three-dimensional element (e.g., sphere, cube) regarded as a fundamental component in the perception of a more complex object. See recognition by components theory. [ first proposed by U.S. psychologist Irving Biederman (1939– )]

Question 6

What is a priming experiment?

Answer 6

Priming research is used to explore the workings of memory, perceptual processing, and how subtle cues affect people’s thinking. In a more general sense, the term “prime” can describe a stimulus used to influence participants’ thinking in some measurable way as part of any psychological experiment.
