NAME¶
teem - simple command-line tools which provide fast and easy access to the
functionality in the various libraries
DESCRIPTION¶
teem-affine: This uses air's AIR_AFFINE macro to print out the value
which stands in the same relationship with the interval [<minOut>,
<maxOut>] as <value> has with the interval [minIn, maxOut].
teem-deconv: Does deconvolution.
teem-airSanity:
teem-cubic:
teem-emap: Creates environment maps based on limn's "checker"
normal quantization methods. By taking into account camera parameters, this
allows for both lights in both world and view space. Solely out of laziness,
the nrrd format is used for specifying the lights, but not to worry: you can
use a simple un-adorned text file, defining one light per line, with 7 values
per light: 0/1 (world/view space), R G B color, and X Y Z position.
teem-gkms: Semi-Automatic Generation of Transfer Functions
teem-idx2pos: Converts from floating-point "index" to
floating-point "position", given the centering of the data (cell vs.
node), the range of positions, and the number of intervals into which position
has been quantized.
teem-ilk: (I)mage (L)inear Trans(X-->K)forms. Applies linear
(homogenous coordinate) transforms to a given image, using the given kernel
for resampling.
teem-miter: A simple but effective little volume renderer.
teem-mrender: A demonstration of hoover, gage, and nrrd measures. Uses
hoover to cast rays through a volume (scalar, vector, or tensor), gage to
measure one of various quantities along the rays, and a specified nrrd measure
to reduce all the values along a ray down to one scalar, which is saved in the
output (double) image.
teem-ninspect: Quick way of seeing what's inside a 3D volume. A color
image of three axis-aligned projections is composed of histogram-equalized and
quantized images of the summation (red), variance (green), and maximum (blue)
intensity projections. If volume is orientation in RAS space, then a standard
orientation is used for projections and projections are upsampled (with box
kernel) to have isotropic pixels.

teem-nrrdSanity:
teem-overrgb: Composites an RGBA nrrd over a background color (or image),
after doing gamma correction, then quantizes to an 8-bit image. Actually, the
input nrrd can have more than 4 values per pixel, but only the first four are
used. If the RGBA nrrd is floating point, the values are taken at face value;
if it is fixed point, the values interpreted as having been quantized (so that
8-bit RGBA images will act as you expect). When compositing with a background
image, the given background image does not have to be the same size as the
input image; it will be resampled (with linear interpolation) to fit.
teem-pos2idx: Converts from floating-point "position" to
floating-point "index", given the centering of the data (cell vs.
node), the range of positions, and the number of intervals into which position
has been quantized.
teem-pprobe: Uses gageProbe() to query scalar or vector volumes at a
single probe location.
teem-qbert: Generates volume datasets friendly to hardware-based volume
renderers. The main value of this is a means of combining the functions of
resampling a dataset to a particular size, measuring first (and optionally
second) derivatives, and doing some semi-intelligent quantization of the
derivative values down to 8-bits (if quantization is desired). The various up
and down sampling, as well as the the VGH measurements, can be done with
various nrrd kernels. Also, histogram-equalized VG and VH scatterplots can be
generated at a specified resolution.
teem-talkweb: Generates HTML pages from slide images and text. This
program takes multiple inputs: a template for the table of contents that will
become "index.html" ("-i"), a template for the pages
generated for each slide e.g. "slide000.html" ("-t"), and
a script text file that contains all the information that will go into the
slide pages. The format of this file is:
- Separator line indicating slide transitions, e.g. "-------------"
- Title of first slide (one line)
- Filename for image to put on first slide (one line)
- Body of HTML text to put with the slide image (multiple lines)
- Separator followed by information for the second slide, and so forth. Textual
subtitutions are performed in the template files, according to the replacement
tags ("-r", see below). Within the slide pages, navigation arrows
are based on remaining command-line options.
teem-tend: Diffusion Tensor Processing and Analysis
teem-undos undos: Converts from DOS text files to normal (converting
LF-CR pairs to just CR), or, with the "-r" option, convert back to
DOS, for whatever sick and twisted reason you'd have to do that. Can also
handle legacy MAC text files (only LF). Unlike the simple sed or perl scripts
for this purpose, this program is careful to be idempotent. Also, this makes
an effort to not meddle with binary files (on which this may be mistakenly
invoked). A message is printed to stderr for all the files actually modified.
teem-ungantry: Gantry tilt be gone! This program is actually of limited
utility: it can only change the tilt by shearing with the X and Z axis fixed,
by some angle "around" the X axis, assuming that (X,Y,Z) is a
right-handed frame.
teem-unu: Utah Nrrd Utilities command-line interface
teem-vprobe: Shows off the functionality of the gage library. Uses
gageProbe() to query various kinds of volumes to learn various measured or
derived quantities. Can set environment variable TEEM_VPROBE_HACK_ZI to limit
probing to a single z slice.
