Gibson 1966: Objects are ecological units that depend on the organism and the environment.

Things that are larger than the body are viewed as extended surfaces. Things smaller than the body are viewed as objects.

Adults do not need to manipulate objects to perceive them.[p138] A pixel map holds no explicit information about objects. The bitmap doesn't say whether two adjacent pixels, for example, come from the same or different objects in the viewed scene.

Edge detection is the first step of object perception, which located discontinuities in the array. Edge classification differentiates which edges are object boundries. Boundary assignment picks out the objects. Spatial and temporal fragmentation make it difficult. [p141]

Gestalt principles:
Common fate: things that move together are grouped together.[p142]
good continuation: smoothly changing contour comprises a unit.

Edge detection is unlearned. [p176]
