Abstract

In today’s rapidly evolving digital landscape, the demand for accurate and contextually relevant subtitles for image and video content, particularly in the medical domain, is increasingly critical. Despite the proliferation of visual data across various platforms, existing captioning systems often struggle due to variations in visual settings, complex temporal relationships, and nuanced semantics. Additionally, challenges such as limited datasets, privacy issues, and specialized annotation requirements make medical image captioning particularly difficult. To tackle these challenges, we investigate cutting-edge deep learning methodologies, specifically Transfer Learning and Transformer models, through a comparative analysis. Specifically, we focus on Transfer Learning through the MedVisionCapturer model and Transformer models using CausalVLM. Our findings reveal that the Transfer Learning model achieves notable performance with a BLEU score of 83.34, CIDEr Score of 89.23, METEOR Score of 43.91, and ROUGE-L value of 73.41 when tested on a limited set of CT scan recordings. In contrast, the Transformer model attains competitive yet lower scores: a BLEU score of 71.42, CIDEr Score of 74.20, METEOR Score of 99.06, and ROUGE-L value of 96.10. Therefore, this work underscores the promise of the advanced models introduced to improve the efficacy of automatic medical image captioning systems, ultimately fostering better health outcomes within an increasingly complex medical landscape.
