CITlab Advanced Layout Analysis Method

Neural Net setting

Allows to choose a specific neural network to be used for finding lines and regions. Choose "Preset" if you are not sure about the options or when working on a new dataset.

Settings

Only available for the "Preset" neural networks.

• Text orientation:
  • Default: it is assumed that all present text is 0° oriented
  • Homogeneous: it is assumed that the text is homogeneously oriented. All text lines have the same orientation: 0°, 90°, 180° or 270°
  • Heterogeneous: text could be oriented heterogeneously, a mix of 0°, 90°, 180° and 270° is possible. Text lines with the same orientation are clustered in the same text regions.
• Use seperators:
  • Default: within a given text region/cell region do not use seperators. If no regions are given, use them.
  • Always: uses seperators also within given regions/cells
  • Never: never uses separator information
