  • Title: Automated medical image modality recognition by fusion of visual and text information.
    Author: Codella N, Connell J, Pankanti S, Merler M, Smith JR.
    Journal: Med Image Comput Comput Assist Interv; 2014; 17(Pt 2):487-95. PubMed ID: 25485415.
    Abstract:
    In this work, we present a framework for medical image modality recognition based on a fusion of both visual and text classification methods. Experiments are performed on the public ImageCLEF 2013 medical image modality dataset, which provides figure images and associated fulltext articles from PubMed as components of the benchmark. The presented visual-based system creates ensemble models across a broad set of visual features using a multi-stage learning approach that best optimizes per-class feature selection while simultaneously utilizing all available data for training. The text subsystem uses a pseudoprobabilistic scoring method based on detection of suggestive patterns, analyzing both the figure captions and mentions of the figures in the main text. Our proposed system yields state-of-the-art performance in all 3 categories of visual-only (82.2%), text-only (69.6%), and fusion tasks (83.5%).
