Line Drawings in Cognition
// note
On Sayim & Cavanagh (https://www.frontiersin.org/articles/10.3389/fnhum.2011.00118/abstract)
Perspective on line drawings, how they are significant:
--> via learned neural codes that spark understanding of an object (theories for whether this came from development in nature that instilled this across different species)
Suggest line drawings are easy to recognize
-> human coactivate same areas for line drawings compared to orientation/edge tuned neurons
-> fast recognition - biederman & ju = fast as photographs
-> not a cultural phenomenon
-> lacking textures/shading yet still look 3d
Why do we recognize line drawings? is it it cultural experience?
-> No, bc Infants, stone age, chimpanzees all recognize
--> Understanding innate “important” contours = information compression. If we were to compress this image to its core important features
Line drawings recognition
--> Detect edges
--> Determine which edges are important to the object
--> Remove certain contours
--> Memory process (junctions)
Edges do not respond to homogeneous regions
--> Contour detector
--> Center surround cell
--> Line details don’t actually exist in the natural world
--> Co-activate same regions
Process side:
--> Determine which edges are important to the object
--> Remove certain contours
--> Memory process (junctions)
--> Lines must represent important info (color, textures, lightness differences)
--> co-activate same neurons
