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


This program evaluates the histogram over a series of 2D images


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

input image(s) to be filtered. For supported file types see Plugin type: 2dimage/io

-o, --out-histogram=(output, required); string

output file name

--min=0; float

minimum of histogram range

--max=65535; float

maximum of histogram range

--bins=65536; ulong

number of histogram bins, set to zero to create a bin for each intensity value availabe in the input data. In this case the histogram range is also evaluated automatically

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 histogram over all consecutively numbered images that follow the numbering pattern inputXXXX.exr and store the output histogram in histo.txt. Use the range [0,256] and 64 bins.

mia-multihist -i input0000.exr -o histo.txt --min 0 --max 256 --bins 64
