HUCVL at MediaEval 2016: Predicting Interesting Key Frames with Deep Models

In MediaEval 2016, we focus on the image interestingness subtask which involves predicting interesting key frames of a video in the form of a movie trailer. We specifically propose three different deep models for this subtask. The first two models are based on fine-tuning two pretrained models, namely AlexNet and MemNet, where we cast the interestingness prediction as a regression problem. Our third deep model, on the other hand, depends on a triplet network which is comprised of three instances of the same feedforward network with shared weights, and trained according to a triplet ranking loss. Our experiments demonstrate that all these models provide relatively similar and promising results on the image interestingness subtask.
