Description

Reads a dense 3D (2D) displacement field, computes the corresponding stationary 3D (2D) velocity field, and writes the resulting vector field.

Command options

Use scaling and squaring (SS) method for exponentiation. (default)

-euler

Use forward Euler method for exponentiation.

-steps <int>

Number of integration steps (2^n in case of SS). (default: 64)

-terms <int>

Number of BCH approximation terms (either 2 or 3). (default: 6)

-iters <int>

Number of BCH update steps. (default: 8)

-smooth

Smooth velocities before each update. (default: off)

-jac

Use Jacobian for Lie bracket computation. (default: off)

Standard options

-v, -verbose [n]

Increase/Set verbosity of output messages. (default: 0)

-debug [level]

-version [major.minor]

Print version and exit or set version to emulate.

-revision

Print revision (or version) number only and exit.

-h, -help

Print help and exit.

Terminal options
