In the above manuscript, the caption for Figure 2 should read as follows:
Figure 2: Comparison of approaches towards heterogeneous and domain specific biomedical and scientific images. This figure highlights different approaches, which have been discussed in this manuscript, towards the heterogeneous (Integrating image data into biomedical text; Automatic segmentation of subfigure image panels for multimodal biomedical document retrieval; Parsing multi-panel collaged figures method for document image understanding; Analysing axis diagrams with nominal and discrete dimensions; Automatic categorization and spatial distribution analysis of biomedical images; Yale Image Finder) and domain specific (Framework for the analysis and segmentation of protein-protein interactions images; Management-based image processing solutions for microscopy data; Ontology based information retrieval using low-level feature extraction; Mining images for the detection and analysis of gel diagrams; Bioimaging for complex networks and pathways analysis; Analysing embedded structural properties of four different classes of biomedical figures) biomedical and scientific images.
