Exercise 5

Both images and free text share the characteristic that they are unstructured information; image processing methods to make the biomedical content in images explicit are very similar to related problems in natural language processing (NLP; Chap. 8). How are image processing methods and NLP similar in terms of (1) computer representation of the raw content? (2) representation of the semantic content? (3) processing of the content (e.g., what is the NLP equivalent of segmentation, or the image processing equivalent of named entity recognition)?
