Create captions based on a series of images I'd like to generate subtitles for a silent film. Is there an open source project out there capable of creating captions based on a series of images (such as a scene from a movie)?

EDIT: thanks for the comments below. To clarify, what i'm looking for is an algorithm which can generate a caption for a sequences of images within a movie  describing what happens in the sequence. This is for preliminary research, so accuracy is less important.
What you might want to look for is called video captioning. Earlier examples from this line of research is:


Venugopalan et. al. Sequence to Sequence – Video to Text, in ICCV 2015
Pasunuru et.al. Multi-Task Video Captioning with Video and
Entailment Generation, in ACL 2017


Below is a screenshot of the results (positive and negative) reported in those papers:



For the ICCV paper, it's not hard to find some implementations, e.g. here.

For more recent results, I would suggest to look into the ActivityNet 2017 Challenge - dense captioning or its 2018 version. Some winning solutions include:


Jointly Localizing and Describing Events for Dense Video Captioning
RUC+CMU: System Report for Dense Captioning Events in Videos


However I am not sure whether any open-source implementation has been released.
