Researchers have developed a novel dual-branch fusion module that operates in the frequency domain to enhance medical visual question answering (VQA). This approach adaptively selects global low-frequency structures and fine-grained high-frequency details from both visual and textual data before generating an answer. By extracting features from different layers of a BiomedCLIP encoder and aligning them with question representations using an InfoNCE objective, the model is trained with a BioBART decoder. The proposed method demonstrates improved performance on the PMC-VQA, VQA-RAD, and SLAKE benchmarks while maintaining an efficient architecture. AI
