  abstract =     {We consider the multi-class object detection
                  approach based on a non-parametric multiplicative
                  kernel, which provides both separation against
                  backgrounds and feature sharing among foreground
                  classes. The training is carried out through the SVM
                  framework. According to the obtained support
                  vectors, a set of linear detectors is constructed by
                  plugging the foreground training samples into the
                  multiplicative kernel. However, evaluating the
                  complete set would be inefficient at runtime, which
                  means that the number of detectors has to be reduced
                  somehow. We propose to reduce that number in a novel
                  way, by an appropriate detector selection
                  procedure. The proposed detection approach has been
                  evaluated on the Belgian traffic sign dataset. The
                  experiments show that detector selection succeeds to
                  reduce the number of detectors to the half of the
                  number of object classes. We compare the obtained
                  performance to the results of other detection
                  approaches and discuss the properties of our
                  approach.},
