# mia-2ddeform(1)

Transform a 2D image by means of a vector field.

## NAME

mia-2ddeform - Transform a 2D image by means of a vector field.

## SYNOPSIS

**mia-2ddeform -i \<in-file\> -o \<out-file\> -t \<transformation\> \[options\]**

## DESCRIPTION

**mia-2ddeform** This program is used to deform a 2D image using a deformation vector field. Input image and deformation field must be of the same size. The transformation formula is 'x -\> x - v(x)'

## OPTIONS

- \-i --in-file=(required, input); io

  input image\
    For supported file types see PLUGINS:2dimage/io

- \-o --out-file=(required, output); io

  transformed  image\
    For supported file types see PLUGINS:2dimage/io

- \-t --transformation=(required, input); io

  transformation vector field\
    For supported file types see PLUGINS:2dvf/io

- \-p --interpolator=bspline:d=3

  image interpolator kernel\
    For supported plugins see PLUGINS:1d/splinekernel

### Help & Info

  *trace* ‐ Function call trace

  *debug* ‐ Debug output

  *info* ‐ Low level messages

  *message* ‐ Normal messages

  *warning* ‐ Warnings

  *fail* ‐ Report test failures

  *error* ‐ Report errors

  *fatal* ‐ Report only fatal errors
