Real-time detection...how? #60

Hi, in the paper you wrote that your system can achieve good real-time detection in real-world applications.

I am wondering how I could use it in real-time given that the MTN module has to process all the video snippets at once, even in test mode. Do you think it is possible to obtain a score for a single feature set (i.e., 16 frames) while still benefiting from the trained MTN module? If so, could you please provide more details?

Thank you!

Sorry about the confusion in the paper. We just refer 'real time' as the inference efficiency (inference time for a single frame). I believe what you mentioned is about online detection/learning. There are works that investigate such problems such as 'Not only Look, but also Listen: Learning Multimodal Violence Detection under Weak Supervision' from Wu et al.
