mia-2dseriesgradvariation {-i string} {-o io} [ options ...]


Given a set of images of temporal sucession, this program evaluates the gradient variation of the pixel-wise time-intensity curves of this series. If the input image set provides a segmentation, then this segmentation can be used to create a bounding box and restrict evaluation to this box.


-i, --in-file=(input, required); string

input segmentation set

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

output file name. For supported file types see Plugin type: 2dimage/io

-k, --skip=0; ulong

Skip files at the beginning

-e, --enlarge-boundary=5; ulong

Enlarge cropbox by number of pixels

-c, --crop

crop image before running statistics

Help & Info

-V, --verbose=warning; dict

verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:

info:Low level messages
trace:Function call trace
fail:Report test failures
error:Report errors
debug:Debug output
message:Normal messages
fatal:Report only fatal errors
--copyright=(); bool

print copyright information

-h, --help=(); bool

print this help

-?, --usage=(); bool

print a short help

--version=(); bool

print the version number and exit


--threads=-1; int

Maxiumum number of threads to use for processing,This number should be lower or equal to the number of logical processor cores in the machine. (-1: automatic estimation).


Evaluate the gradient-variation image of the bounding box surrounding the segmentation from a series 'segment.set'. The bounding box will be enlarged by 3 pixels in all directions. Store the image in OpenEXR format.
