Document Summary
Perceptual system not concerned with determining the objects image on the retina. Its goal is to determine the object that created the image. Inverse projection problem: the task of determining the object responsible for a particular image on the retina, involves starting with the retinal image and extending rays out from the eye. Segregation: separating one area or object from another. Viewpoint invariance: the ability to recognize an object seen at different viewpoints. Perceptual organization: process by which elements in our environment become perceptually grouped to create out perception of objects, involves two components: Grouping: visual events are "put together" into units or objects, rules for grouping: Black area more likely to be seen as gure because it is meaningful. Doesn"t occur when meaningfulness is taken away by turning the gure upside-down. 2d retinal images are ambiguous: a particular retinal image can be created by an in nite number of objects.
