argyll

Color Management System, calibrator and profiler

Argyll is an experimental, open source, ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, film recorders and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants observer types, and paper fluorescent whitener additive compensation. Profiles can also incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance model, a unique gamut mapping algorithm, and a wide selection of rendering intents. It also includes code for the fastest portable 8 bit raster color conversion engine available anywhere, as well as support for fast, fully accurate 16 bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.

mrtrix

diffusion-weighted MRI white matter tractography

Set of tools to perform diffusion-weighted MRI white matter tractography of the brain in the presence of crossing fibres, using Constrained Spherical Deconvolution, and a probabilisitic streamlines algorithm. Magnetic resonance images in DICOM, ANALYZE, or uncompressed NIfTI format are supported.

sptk

speech signal processing toolkit

The Speech Signal Processing Toolkit (SPTK) is a suite of speech signal processing tools for UNIX environments developed by the SPTK working group and some graduate students in Nagoya Institute of Technology.

num-utils

programs for dealing with numbers from the command line

The 'num-utils' are a set of programs for dealing with numbers from the Unix command line. Much like the other Unix command line utilities like grep, awk, sort, cut, etc. these utilities work on data from both standard in and data from files. Includes these programs: * numaverage: A program for calculating the average of numbers. * numbound: Finds the boundary numbers (min and max) of input. * numinterval: Shows the numeric intervals between each number in a sequence. * numnormalize: Normalizes a set of numbers between 0 and 1 by default. * numgrep: Like normal grep, but for sets of numbers. * numprocess: Do mathematical operations on numbers. * numsum: Add up all the numbers. * numrandom: Generate a random number from a given expression. * numrange: Generate a set of numbers in a range expression. * numround: Round each number according to its value.
