Feature Detection#

Feature Detection is always the first step in tobac. These pages serve to go more in depth on Feature Detection parameters and options and the implications of using each of them.

    • Thresholds
    • Minimum Threshold Number
    • Feature Position
    • Filtering Options
    • Minimum Distance
  • Feature Detection Output
  • How multiple thresholds changes the features detected

    • Generate Feature Data
    • Single Threshold
    • Multiple Thresholds
  • How n_min_threshold changes what features are detected
