This page lists the various optic flow and interactive vision computations on the site. The optic flow movies were made with help from students: Graduate student Colin McKinney and undergraduate U of I student Alys Rodriguez. Summer 2011 REU students: Dylan Macuk, Gabriel Porrata, Kraig Thomas, Bridget Toomey, with help from graduate student Andrew Greene

REU11

A general optic flow movie showing a moving retina with the image of an object projected on it. It also shows the image on the "flat retina" or homogeneous coordinates for the retina. (This is like a flat contact lens in front of your eye.) This motion is complicated and the retinal flow is, too. There is motion, there is pursuit, but there is a lot going on...

Straight ahead flow. This movie shows the image of a bunch of random dots as you move straight toward one of them. There is no pursuit in this case.

Orthogonal cases of optic flow

The optic flow of an observer translating laterally observing objects both closer and farther than the fixate. This is link looking at a farm house out the side window of a moving car. The blue trees seem to move with you and the red mailbox seems to move opposite your translation. This is the situation that the motion pursuit theory gives a good account.
