v3grow - 3D region growing

SYNOPSIS

v3grow [if=] [of=] [s=] [l=] [th=] [-2D] [-v] [nt=] [m=] [M=] [-s]

DESCRIPTION

v3grow performs an adaptive 3D region growing starting from a seed point. A neighboring voxel is added to the grown region if its intensity is below a threshold ([th=]) and at least [nt=] of its neighbors also fall below that threshold. The threshold parameter ([th=]) is automatically incremented or decremented based on the expected volume of the region. If the region grows larger than the maximum allowed volume [M=], we assume that the region has "leaked" into the neigbouring regions and the intensity threshold is automatically decremented.

OPTIONS

	if=		input image
	of=		output image
	l=		region label
	th=		threshold value for growing
	-2D		2D region growing
	-v		verbose output
	nt=		neighbor thresh-debug only
	m=		minimum allowed volume
	M=		maximum allowed volume
	-s		grow if voxel-seed < thresh (default: voxel < thresh)
