The continual improvement of object recognition systems has resulted in an
increased demand for their application to problems which require an exact
pixel-level object segmentation. In this paper, we illustrate an example of
an object class recognition and segmentation system which is trained using
weakly supervised training data, with the goal of examining the influence
that different model choices can have on its performance. In order to achieve
pixel-level labeling for rigid and deformable objects, we employ regions generated
by unsupervised segmentation as the spatial support for our image
features, and explore model selection issues related to their representation.
Numerical results for pixel-level accuracy are presented on two challenging
and varied datasets.
