Filter Ridge Structures

Uses an image filter to make a probabilistic image of ridge structures.

Parameters:
  • input_image (niimg) – Image containing structure-of-interest
  • structure_intensity ({'bright', 'dark', 'both}) – Image intensity of structure-of-interest’
  • output_type ({'probability','intensity'}) – Whether the image should be normalized to reflect probabilities
  • use_strict_min_max_filter (bool, optional) – Choose between the more specific recursive ridge filter or a more sensitive bidirectional filter (default is True)
  • save_data (bool, optional) – Save output data to file (default is False)
  • overwrite (bool) – Overwrite existing results (default is False)
  • output_dir (str, optional) – Path to desired output directory, will be created if it doesn’t exist
  • file_name (str, optional) – Desired base name for output files with file extension (suffixes will be added)
Returns:

Dictionary collecting outputs under the following keys (suffix of output files in brackets)

  • ridge_structure_image: Image that reflects the presensence of ridges in the image (_rdg-img)
Return type:

dict
