Multimodal Transformer for Comics Text-Cloze
Emanuele Vivoli Joan Lafuente Baeza Ernest Valveny Llobet Dimosthenis Karatzas
This work explores a closure task in comics, a medium where visual and
textual elements are intricately intertwined. Specifically, Text-cloze refers
to the task of selecting the correct text to use in a comic panel, given its
neighboring panels. Traditional methods based on recurrent neural networks have
struggled with this task due to limited OCR accuracy and inherent model
limitations. We introduce a novel Multimodal Large Language Model
(Multimodal-LLM) architecture, specifically designed for Text-cloze, achieving
a 10% improvement over existing state-of-the-art models in both its easy and
hard variants. Central to our approach is a Domain-Adapted ResNet-50 based
visual encoder, fine-tuned to the comics domain in a self-supervised manner
using SimCLR. This encoder delivers comparable results to more complex models
with just one-fifth of the parameters. Additionally, we release new OCR
annotations for this dataset, enhancing model input quality and resulting in
another 1% improvement. Finally, we extend the task to a generative format,
establishing new baselines and expanding the research possibilities in the
field of comics analysis.
