Semantic concept based video retrieval using convolutional neural network

Retrieval of videos efficiently and effectively has become a challenging issue nowadays and dealing with multi-concept videos is the center of focus. The aim of the work presented here is to propose an improved semantic concept-based video retrieval method using a novel ranked intersection filtering technique and a foreground driven concept co-occurrence matrix. In the proposed ranked intersection filtering technique, an intersection of ranked concept probability scores is taken from key-frames associated with a query shot to identify concepts to be used in retrieval. Convolutional neural network is used as a baseline. The proposed method is implemented using a classifier built with a fusion of asymmetrically trained deep CNNs to deal with data imbalance problem, a novel foreground driven concept co-occurrence matrix to exploit concept co-occurrence information and a ranked intersection filtering approach. Performance is evaluated by a measure, mean average precision on TRECVID multi-label dataset. The results are compared with state-of-the-art other existing methods in its class and shown its superiority.
