java.lang.Object

sc.fiji.snt.tracing.auto.AbstractAutoTracer

sc.fiji.snt.tracing.auto.AbstractGWDTTracer<T>

sc.fiji.snt.tracing.auto.GWDTTracer<T>

Type Parameters:

T - pixel type

All Implemented Interfaces:

AutoTracer

public class GWDTTracer<T extends net.imglib2.type.numeric.RealType<T>>
extends AbstractGWDTTracer<T>

In-memory GWDT tracer using array storage.

Fast but memory-intensive. Best for images < 1GB. Uses APP2-style algorithm: Gray-Weighted Distance Transform, Fast Marching, and hierarchical pruning.

spacing - voxel dimensions [x, y, z] in physical units

GWDTTracer

public GWDTTracer(net.imagej.ImgPlus<T> source)

Creates a new GWDTTracer from an ImgPlus.

Parameters:

source - the grayscale image to trace

GWDTTracer

public GWDTTracer(net.imglib2.RandomAccessibleInterval<T> source)
