limereg - Lightweight Image Registration
limereg --rfile <reference image> --tfile
<template image> [OPTIONS]
limereg 1.4.1
limereg - Lightweight Image Registration Performs a simple rigid
image registration. The image files must have equal size. Supported image
formats: *.bmp, *.dib, *.jpeg, *.jpg, *.jpe, *.jp2, *.png, *.pbm, *.pgm,
*.ppm, *.sr, *.ras, *.tiff, *.tif.
- --help
- Show usage information.
- --version
- Show application version and copyright information.
- --rfile arg
- Template image file (will be transformed). The template and reference
images must be equal in size.
- --tfile arg
- Reference image file (will be matched against). The template and reference
images must be equal in size.
- --outfile
arg
- Output image file (optional). Gives the option to save the registered
template image as grayscale result.
- --maxiter
arg
- Max. amount of iterations. [Optional parameter, default: 150]
- --levels
arg
- Amount of levels in the multilevel pyramid of shrinked image copies. 0
means autodetect by the formula log2(ImageWidth/32). [Optional parameter,
default: 0]
- --maxrot
arg
- Max. expected rotation in degrees. Used for internal optimizations in DSP
calculation mode. If a rotation value will become necessary that is higher
than specified here, the algorithm will still succeed but the calculation
speed will slow down). [Optional parameter, default: 20]
- --maxtrans
arg
- Max. expected translation in percent. Used for internal optimizations in
DSP calculation mode. If a translation value will become necessary that is
higher than specified here, the algorithm will still succeed but the
calculation speed will slow down). [Optional parameter, default: 30]
- --invert
- Invert the internal grayscale representation. Best registration results
are usually obtained with bright content on a dark background, consider
setting this parameter, if you have dark content on a bright background.
This setting affects only the internal operation, it will not be visible
on GUI or file output images. [Flag parameter]
- --stopsens
arg
- Sensitivity of the STOP criteria for the gauss-newton algorithm. [Optional
parameter, use ranges between 1 (not sensitive, stops early) to 0.0001
(very sensitive) default: 0.1]
- --cdn arg
- Clip dark pixels until (including) the given luminance to zero. This
reduces image sensor noise in the usually uninteresting dark pixels. A
high value optimizes data compression and calculation performance at the
cost of calculation accuracy. [Optional parameter, range 0...255, 0
disables any clipping, default: 10]
- --nogui
- If active no GUI output will be shown. Use this for batch registration of
several images. [Flag parameter]
limereg --tfile t.jpg --rfile r.png Shifts/Rotates t.jpg for
alignment with r.png and displays the result.
limereg --tfile t.bmp --rfile r.tif --nogui --outfile o.jpg
Outputs the result to o.jpg, no GUI display. :
