TRECVid 2013 experiments at Dublin City University (2013)

Abstract In a move away from previous years’ participation in TRECVid ([1] [2] [3]), this year our team focused on the instance search task (INS). We improved our system from last year by applying large vocabulary quantization, soft assignment of visual words, spatial verifications and query expansion. Overall, four automatic runs have been submitted for evaluation. In this paper, we present first our system, then we discuss the results and findings of our experiments.
