Expand description

Calculate proximity maps using curvature at the brain surface

This is the main entry point matching QSMART’s calculate_curvature function.

§Arguments

  • mask - Binary brain mask
  • prox1 - Initial proximity map from Gaussian smoothing
  • lower_lim - Clamping value for proximity (default 0.6)
  • curv_constant - Scaling constant for curvature (default 500)
  • sigma - Kernel size for smoothing curvature
  • nx, ny, nz - Volume dimensions

§Returns

Modified proximity map incorporating curvature-based edge weighting
