We present a new algorithm to detect pedestrians in
still images utilizing covariance matrices as object descriptors.
Since the descriptors do not form a vector space, well known
machine learning techniques are not well suited to learn the
classifiers. The space of d-dimensional nonsingular covariance
matrices can be represented as a connected Riemannian manifold.
The main contribution of the paper is a novel approach for
classifying points lying on a connected Riemannian manifold
using the geometry of the space. The algorithm is tested on
INRIA and DaimlerChrysler pedestrian datasets where superior
detection rates are observed over the previous approaches.
