LOCUS Demo

Two “different” classes

Class “Car Side Views” Class “Car Rears”

Morphing within a class We can interpolate between model

instance’s parameters (gradual change of the deformation field and pixel colors)

This gives us a nice morphing effect.

LOCUS applied to a video

Mask Edge Map

Every video frame is treated as a separate class instance.

Using motion and tracking cues So far we have derived models by treating

each image as an independent instance of our model.

When segmenting videos, we can improve results by making use of the fact that a video is a continuous model change.
