This study focus on the image captioning problem in Vietnamese. Indetail, an empirical study of grid-based and region-based feature extraction approaches using currentstate-of-the-art object detection methods is investigated to explore the suitable way to represent theimages in the model space. Each feature type represents images, and the image captioning task istrained using the Transformer-based model. The effectiveness of different feature types is exploredon two Vietnamese datasets: UIT-ViIC and VieCap4H, the two standard benchmark datasets. Theexperimental results show crucial insight into the feature extraction task for image captioning inVietnamese.
