Parameter Selection¶

This page points to the upstream guidance for choosing GeFolki parameters.

Primary source¶

• manual_gefolki_english.pdf

Where to read¶

• Manual, section DESCRIPTION OF THE MAIN STEP : FLOW CALULATION BY GEFOLKI This is the main parameter reference for the algorithm.
• Manual, example parameter structure The para = struct(...) block shows the original recommended parameter layout used by the upstream MATLAB implementation.

Parameter topics covered there¶

Use the manual’s numbered list in that section for:

• radius Window-size tradeoff between robustness and local detail.
• levels Pyramid depth as a function of the maximum displacement to estimate.
• iter Number of gradient-based minimization iterations.
• contrast_adapt When contrast inversion handling should be enabled for heterogeneous imagery.
• rank Rank-filter window guidance and typical values.

Why this page is intentionally brief¶

The upstream manual already gives the authoritative conceptual guidance for these parameters. This local documentation keeps the explanation layer lightweight and points readers back to the original source instead of restating it inconsistently.
