Find Boundaries Between Regions on a Surface

This generic function identifies boundaries between different regions or parcellations on a surface. The implementation depends on the class of the input object.

Usage

findBoundaries(x, method = "midpoint", ...)

# S4 method for class 'NeuroSurface'
findBoundaries(x, method = c("midpoint", "edge_vertices", "faces"), ...)

Arguments

x

A NeuroSurface object whose data slot contains integer ROI labels for each vertex.

method

Boundary method passed to find_roi_boundaries. One of "midpoint" (default, crisp single-width contours), "edge_vertices", or "faces".

...

Additional arguments passed to find_roi_boundaries.

Value

An object containing boundary information. The specific structure depends on the method implementation.

A list as returned by find_roi_boundaries.

Details

This function provides a high-level interface for finding boundaries between different regions on a surface mesh. It typically returns coordinates and metadata describing the boundaries between regions.
