PSYB51H3 Study Guide - Principles Of Grouping, Extrastriate Cortex, Illusory Contours
Document Summary
Middle vision: goal of middle vision is to organize the elements of a visual scene into groups that we can then recognize as objects. Finding edges: the occasional lack of an edge does not bother our visual systems, different bits of information are then combined to make the system"s best guess about the preference of a contour, ex. Texture segmentation and grouping: texture segmentation, carving an image into regions of common texture properties, two of the strongest principles of gestalt grouping, similarity. Image chunks that are similar to each other (in a number of fea- tures: coulour, size, aspects of form) will be more likely to group together: proximity. Items near each other are more likely to group together: two of the somewhat weaker principles of gestalt grouping, parallelism, parallel contours are likely to belong to the same figure, symmetry.
