This paper describes the experiments carried out by the UC3M team for the TRECVID 2010 high-level feature extraction task. In our previous participations in TRECVID, we have developed a modular system to facilitate the testing of several functionalities. This year we have selected a simple system configuration and we have added some elements expected to provide an additional advantage. For instance, 1) different kinds of histogram based features have been included in the system, both with a late fusion scheme and with a spatial pyramid matching configuration; 2) according to the nature of the low level features, different kernels have been used to train a set of non-linear SVMs; and, 3) to combine the outputs of the trained SVMs, two different fusion strategies have been taken into account, an average combinatio
