Constructor Details

Steepest

public Steepest(SlidingBuffer<?> buffer,
 WatershedEncoding encoder,
 boolean do3D,
 boolean bigNeighborhood,
 Optional<ObjectMask> objectMask)

Creates a Steepest instance for a specific buffer.

Parameters:

buffer - the SlidingBuffer to process

encoder - the WatershedEncoding to use for encoding directions

do3D - whether to perform 3D processing

bigNeighborhood - if true, use 8-Connectivity instead of 4 in 2D, and 26-connectivity instead of 6 in 3D, as per NeighborhoodFactory

objectMask - an optional ObjectMask to restrict processing

Method Details

steepestDescent

public int steepestDescent(Point3i point,
 int val,
 int indxBuffer)

Calculates the steepest descent direction for a given point.

Parameters:

point - the Point3i to calculate the steepest descent for

val - the value at the given point

indxBuffer - the buffer index for the given point

Returns:

the encoded direction of steepest descent
