Dublin City University and Partners' participation in the INS and VTT Tracks at TRECVid 2016
Abstract: Dublin City University participated with a consortium of colleagues from NUI Galway and Universitat Polit`ecnica de Catalunya in two tasks in TRECVid 2016, Instance Search (INS) and Video to Text (VTT). For the INS task we developed a framework consisting of face detection and representation and place detection and representation, with a user annotation of top-ranked videos. For the VTT task we ran 1,000 concept detectors from the VGG-16 deep CNN on 10 keyframes per video and submitted 4 runs for caption re-ranking, based on BM25, Fusion, Word2Vec and a fusion of baseline BM25 and Word2Vec. With the same pre-processing for caption generation we used an open source image-to-caption CNN-RNN toolkit NeuralTalk2 to generate a caption for each keyframe and combine them. ; The work reported here is based on research conducted with the support of Science Foundation Ireland under grant numbers SFI/12/RC/2289 (Insight Centre) and SFI/13/RC/2106 (ADAPT Centre). ; non-peer-reviewed
