Document Summary

Lecture 24 visual guidance of locomotion and sound. Motion informs us about: (two components of motion is speed and direction) Vector field: fancy way of saying that at each x-y location of the image, you"re going to have an arrow. This is what the motion content is going to look like. That kind of motion is useful, because it tells you which direction you"re headed within the scene and also, as a result, we can tell if we"re in a collision course with another object. Doesn"t always have to be moving it could just be a tree or a table you still have to worry about the collision course) this is what we call an optic flow. How soon a collision is likely to occur. Forward motion it would look like and expansion (outward flow) in the image look like.
