Free nrpg ratio software for linux

gtranscode is a GTK+ GUI (graphical use interface) front-end for transcode written in order to make this powerful tool easier to use. Transcode is a powerful video and audio processing tool that can read in just about any format of video and/or audio and convert to just as many different formats. In addition to transcodes extremely flexible modular concept for reading/writing different formats and codecs, it can apply filters, do re-sampling, resizing, cropping, and more. The cost from all this comes in the form of over 100 command line options but gtranscode aims to simplify.
Main features:
- organized layout to reduce confusion
- supports all of the options that most users will want
- uses tcprobe -i (from transcode package) to summarize information about input file before processing
- shows the equivalent transcode command line for troubleshooting and familiarizing users with command line options
- any extra options not supported by the GUI can be manually entered in the entry box before hitting "GO"
- automatic "maintain aspect ratio" calculations
- automatic "projected filesize" calculations based on bitrates
Enhancements:
- added much needed cancel button to progress window
- added capability to tcprobe an entire directory and add the number of frames up. This allows a directory to be transcoded without the progress bar saying NaN.

Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players.
SRC is capable of arbitrary and time varying conversions ; from downsampling by a factor of 256 to upsampling by the same factor. Arbitrary in this case means that the ratio of input and output sample rates can be an irrational number. The conversion ratio can also vary with time for speeding up and slowing down effects.
SRC provides a small set of converters to allow quality to be traded off against computation cost. The current best converter provides a signal-to-noise ratio of 97dB with -3dB passband extending from DC to 96% of the theoretical best bandwidth for a given pair of input and output sample rates.
Since the library has few dependencies beyond that provided by the standard C library, it should compile and work on just about any operating system. It is know to work on Linux, MacOSX, Win32 and Solaris. With some relatively minor hacking it should also be relatively easy to port it to embedded systems and digital signal processors.
In addition, the library comes with a comprehensive test suite which can validate the performance of the library on new platforms.
Enhancements:
- configure.ac Win32/Makefile.mingw.in
- Add preliminary support for compiling on Win32 using MinGW.
- configure.ac
- Bump version to 0.1.2.
- Add --enable-gcc-werror configure option.
- examples/sndfile-resample.c tests/src-evaluate.c
- Use ISO C standard function remove instead of unlink.
- Win32/Makefile.msvc
- Add the top level directory to the include path (for sndfile.h).

RPhoto is a small software aiming at the easy handling of digital cameras photos. (RPhoto is the next generation of IMPhoto).
RPhotos origin resides in the lack of a simple software capable of cropping photos with a constant ratio, to avoid white borders when printing.
RPhoto is distributed under the GPL licence. It allows you to use and distribute freely this software, within the respect of the GPL licence.
Main features:
- Crop images with a constant width / height ratio (by example 4:3 for numeric photos)
- Rotate / Flip photos
- Lossless crop / rotate / flip operations.
- Available under Linux and Windows.
Enhancements:
- This release adds the ability to correct a bad inclination of a picture by drawing a vertical or horizontal line, the modification of comments, Exif tags, undo last operations, and a few bugfixes.

Statistics::ROC is a Perl module with receiver-operator-characteristic (ROC) curves with nonparametric confidence bounds.

SYNOPSIS

use Statistics::ROC;

my ($y) = loggamma($x);
my ($y) = betain($x, $p, $q, $beta);
my ($y) = Betain($x, $p, $q);
my ($y) = xinbta($p, $q, $beta, $alpha);
my ($y) = Xinbta($p, $q, $alpha);
my (@rk) = rank($type, @r);
my (@ROC) = roc($model_type,$conf,@val_grp);

This program determines the ROC curve and its nonparametric confidence bounds for data categorized into two groups. A ROC curve shows the relationship of probability of false alarm (x-axis) to probability of detection (y-axis) for a certain test. Expressed in medical terms: the probability of a positive test, given no disease to the probability of a positive test, given disease. The ROC curve may be used to determine an optimal cutoff point for the test.
The main function is roc(). The other exported functions are used by roc(), but might be useful for other nonparametric statistical procedures.

loggamma

This procedure evaluates the natural logarithm of gamma(x) for all x>0, accurate to 10 decimal places. Stirlings formula is used for the central polynomial part of the procedure. For x=0 a value of 743.746924740801 will be returned: this is loggamma(9.9999999999E-324).

betain

Computes incomplete beta function ratio

Remarks:
Complete beta function: B(p,q)=gamma(p)*gamma(q)/gamma(p+q)
log(B(p,q))=ln(gamma(p))+ln(gamma(q))-ln(gamma(p+q))

Incomplete beta function ratio:
I_x(p,q)=1/B(p,q) * int_0^x t^{p-1}*(1-t)^{q-1} dt

--> log(B(p,q)) has to be supplied to calculate I_x(p,q)
log denotes the natural logarithm
$beta = log(B(p,q))
$x = x
$p = p
$q = q
The subroutine returns I_x(p,q). If an error occurs a negative value
{-1,-2} is returned.

Betain

Computes the incomplete beta function by calling loggamma() and betain().

xinbta

Computes inverse of incomplete beta function ratio

Remarks:

Complete beta function: B(p,q)=gamma(p)*gamma(q)/gamma(p+q)
log(B(p,q))=ln(gamma(p))+ln(gamma(q))-ln(gamma(p+q))

Incomplete beta function ratio:
alpha = I_x(p,q) = 1/B(p,q) * int_0^x t^{p-1}*(1-t)^{q-1} dt

--> log(B(p,q)) has to be supplied to calculate I_x(p,q)
log denotes the natural logarithm
$beta = log(B(p,q))
$alpha= I_x(p,q)
$p = p
$q = q
The subroutine returns x. If an error occurs a negative value {-1,-2,-3}
is returned.

Xinbta

Computes the inverse of the incomplete beta function by calling loggamma() and xinbta().

rank

Computes the ranks of the values specified as the second argument (an array). Returns a vector of ranks corresponding to the input vector. Different types of ranking are possible (high, low, mean), and are specified as first argument. These differ in the way ties of the input vector, i.e. identical values, are treated:

high:

replace ranks of identical values with their highest rank

low:

replace ranks of identical values with their lowest rank

mean:

replace ranks of identical values with the mean of their ranks

roc

Determines the ROC curve and its nonparametric confidence bounds. The ROC curve shows the relationship of "probability of false alarm" (x-axis) to "probability of detection" (y-axis) for a certain test. Or in medical terms: the "probability of a positive test, given no disease" to the "probability of a positive test, given disease". The ROC curve may be used to determine an "optimal" cutoff point for the test.

The routine takes three arguments:

(1) type of model: decrease or increase, this states the assumption that a higher (increase) value of the data tends to be an indicator of a positive test result or for the model decrease a lower value.
(2) two-sided confidence interval (usually 0.95 is chosen).
(3) the data stored as a list-of-lists: each entry in this list consits of an "value / true group" pair, i.e. value / disease present. Group values are from {0,1}. 0 stands for disease (or signal) not present (prior knowledge) and 1 for disease (or signal) present (prior knowledge). Example: @s=([2, 0], [12.5, 1], [3, 0], [10, 1], [9.5, 0], [9, 1]); Notice the small overlap of the groups. The optimal cutoff point to separate the two groups would be between 9 and 9.5 if the criterion of optimality is to maximize the probability of detection and simultaneously minimize the probability of false alarm.

Returns a list-of-lists with the three curves: @ROC=([@lower_b], [@roc], [@upper_b]) each of the curves is again a list-of-lists with each entry consisting of one (x,y) pair.

Examples:

$,=" ";
print loggamma(10), "n";
print Xinbta(3,4,Betain(.6,3,4)),"n";

@e=(0.7, 0.7, 0.9, 0.6, 1.0, 1.1, 1,.7,.6);
print rank(low,@e),"n";
print rank(high,@e),"n";
print rank(mean,@e),"n";

@var_grp=([1.5,0],[1.4,0],[1.4,0],[1.3,0],[1.2,0],[1,0],[0.8,0],
[1.1,1],[1,1],[1,1],[0.9,1],[0.7,1],[0.7,1],[0.6,1]);
@curves=roc(decrease,0.95,@var_grp);
print "$curves[0][2][0] $curves[0][2][1] n";

- Now release 2.0 is a liveDVD, It features a lot of new or up to date tools for auditing and testing a network, from scanning and discovering to exploiting vulnerabilities
- Kcpentrix is based on SLAX 5, a Slackware live Dvd
- The Powerful modularity which Kcpentrix uses, allow us to easily customize our version, and include whichever modules we need.
- KCPENTRIX 2.0 is the most inovative and promising KCPENTRIX ever. It switched to 2.6 kernel line. Zisofs compression was replaced by SquashFS, which provides better compression ratio and higher read speed.

RenderDotC project is a world class photorealistic renderer designed to meet the demands of special effects for film. The primary reason people give for choosing RenderDotC is its favorable price per performance ratio. Moreover, RenderDotC scores high marks on everything that matters for a production renderer:
Main features:
Image Quality
- Images produced with RenderDotC possess that indescribable yet beautiful quality that some people refer to as "the RenderMan look". All phenomena that are prone to aliasing artifacts are effectively anti-aliased and noise is kept to a minimum.
Speed
- RenderDotC was designed in the 1990s to take advantage of the current hardware and software technologies. Its CPU and memory performance is unsurpassed by all renderers in its class.
Robustness
- There are hundreds of details to get right when developing a renderer and that only comes with maturity. RenderDotC has been shipping since 1996 and has proven itself on complex scenes from feature films from The Matrix to Orange County.
Features
- The RenderMan standard prescribes a rich set of geometric primitives and features. RenderDotC provides all of these plus some exclusive features such as NURB curves, DSO shadeops that can call built-in functions, and complete support for extended headroom rendering.
Flexibility
- Being RenderMan-compliant, RenderDotC supports user-programmable shading. It also has other plug-in interfaces including DSO shadeops, procedural primitives, and display drivers. Since shading is decoupled from hiding, one can easily tune the speed/quality tradeoffs of each.
Price
- RenderDotC is priced competitively for both the film and broadcast markets. When considering price, its important to take into account speed. A faster renderer means that the same number of frames can be produced per hour with a smaller render farm. Fewer computers to purchase and maintain further reduces the bottom line.
Support
- As a company, Dot C Software has been around since 1992. Our customers needs come first and we have the agility to respond to requests quickly. The people who wrote RenderDotC are the same ones that provide customer support. At Dot C we make software, period. We do not compete with our customers in the arena of computer graphics production.
Enhancements:
- Improved statistical output.
- Optional non raster-oriented dicing.
- The ability to specify motion factor as a dicing attribute, and user-defined placement of output on X.
- The Windows installer now sets up the environment.
