                  Detection of 3D primitives in a single image
3D primitives are objects whose shape is described by a rigid geometric
configuration of solid faces, parameterized only by anisotropic scaling. I will
describe ongoing work towards simultaneous detection, pose estimation, and
recovery of relative scaling of such primitives from a single image. Our
approach relies on a graphical model that represents the primitive class. The
model captures constraints imposed by the model, and uses an efficient
implementation of approximate inference to select a subset of image features
consistent with a detection hypothesis. We combine this idea with a novel
method for pose estimation, that uses example-based inference jointly with more
traditional approaches. The resulting system is capable of detecting objects in
the presence of clutter, occlusions, and noise.
