Visual Intelligence: Theories and Models

Description

This lecture covers the evolution of vision theories from the 19th to the 20th century, including Structuralism, Gestaltism, and Ecological approaches. It delves into the concepts of Nativism vs. Empiricism, Atomism vs. Holism, and Organism vs. Environment, highlighting the works of prominent figures like Wilhelm Wundt, Wolfgang Kohler, and James J Gibson. The lecture also explores the idea of perception as modeling the environment, discussing visual completion, illusions, and mental models proposed by Kenneth Craik in 1943.

Visual perception

Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have problems with visual perceptual processing even if they have 20/20 vision.

Perception

Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.

Atomism

Atomism (from Greek ἄτομον, atomon, i.e. "uncuttable, indivisible") is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms. References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions. Leucippus is the earliest figure whose commitment to atomism is well attested and he is usually credited with inventing atomism. He and other ancient Greek atomists theorized that nature consists of two fundamental principles: atom and void.

Structuralism (psychology)

Structuralism in psychology (also structural psychology) is a theory of consciousness developed by Wilhelm Wundt and his student Edward Bradford Titchener. This theory was challenged in the 20th century. Structuralism as a school of psychology seeks to analyze the adult mind (the total sum of experience from birth to the present) in terms of the simplest definable components and then to find how these components fit together to form more complex experiences as well as how they correlate to physical events.

Gestalt psychology

Gestalt psychology, gestaltism, or configurationism is a school of psychology that emerged in the early twentieth century in Austria and Germany as a theory of perception that was a rejection of basic principles of Wilhelm Wundt's and Edward Titchener's elementalist and structuralist psychology. As used in Gestalt psychology, the German word Gestalt (gəˈʃtaelt,-'Stɑːlt,-ˈʃtɔːlt,-ˈstɑːlt,-ˈstɔːlt ɡəˈʃtalt; meaning "form") is interpreted as "pattern" or "configuration".
