Figure 5From: A framework for biomedical figure segmentation towards image-based document retrievalImage processing. A sample figure extracted from PMID16003391 describing our image processing algorithm. (A) Original image; (B) Optimum threshold value computed using the triangle method developed by Zack et al. [22]. (C) Binarization result using the threshold value calculated by the triangle method [22]; (D) Minimum area rectangles bounding the connected components in the figure.Back to article page
