ATR (4) - Layout Analysis
Layout analysis is a computer vision tasks that allows us to identify the structure of a document and localize the lines of text. We generate a series of x and y coordinates corresponding to regions/lines on the image, which we associate to a corresponding labels.
Text line segmentation is mandatory in most ATR systems, but without a good line segmentation, transcription performances will not be sufficient. For example, lines can be missed, read in the wrong order, or even broken down into several lines.
Synonyms: “segmentation”, “zoning”, “document analysis”, “optical layout analysis”.
