The octave-forge package is the result of The GNU Octave Repositry project, which is intended to be a central location for custom scripts, functions and extensions for GNU Octave. contains the source for all the functions plus build and install scripts. This is level-set. Routines for calculating the time-evolution of the level-set equation and extracting geometric information from the level-set function.

RPy is a very simple, yet robust, Python interface to the R Programming Language. It can manage all kinds of R objects and can execute arbitrary R functions (including the graphic functions). All the errors from the R language are converted to Python exceptions. Any module that later were installed on the R system, can easily be used from within Python, without introducing any changes.

Set::IntSpan manages sets of integers. It is optimized for sets that have long runs of consecutive integers. These arise, for example, in .newsrc files, which maintain lists of articles: alt.foo: 1-21,28,31 alt.bar: 1-14192,14194,14196-14221 Sets are stored internally in a run-length coded form. This provides for both compact storage and efficient computation. In particular, set operations can be performed directly on the encoded representation.

The Set::IntSpan module represents sets of integers as a number of inclusive ranges, for example '1-10,19-23,45-48'. Because many of its operations involve linear searches of the list of ranges its overall performance tends to be proportional to the number of distinct ranges. This is fine for small sets but suffers compared to other possible set representations (bit vectors, hash keys) when the number of ranges grows large. Set::IntSpan::Fast tries to fix that.

Mpmath is a pure-Python library for multiprecision floating-point arithmetic. It provides an extensive set of transcendental functions, unlimited exponent sizes, complex numbers, interval arithmetic, numerical integration and differentiation, root-finding, linear algebra, and much more. Almost any calculation can be performed just as well at 10-digit or 1000-digit precision, and in many cases mpmath implements asymptotically fast algorithms that scale well for extremely high precision work. If available, mpmath will (optionally) use gmpy to speed up high precision operations.

From the histring README: This program simply highlights strings using ANSI terminal escape codes. It started out as sample code for using regular expressions but it turned out that I used it so much that I thought it warrented a release. One of the most common things I use the program for is helping me parse the output of grep and diff. I think that this programs functionality should be folded in to those programs but until then histring does the job nicely.

Digital TV initial scanning tables are used to speed up scanning for DTV frequencies. Most dvb applications rely on them. This supplies initial data for certain regions so that the dvb applications in question only scan those known frequencies, saving a lot of time scanning. These tables however need to be kept up to date by users. This repository is maintained by Olliver Schinagl (https://github.com/oliv3r) on behalf of the LinuxTV.org project.

Gavl is short for Gmerlin Audio Video Library. It is a low level library, upon which multimedia APIs can be built. Gavl handles all the details of audio and video formats like colorspaces, samplerates, multichannel configurations etc. It provides standardized definitions for those formats as well as container structures for carrying audio samples or video images inside an application. In addition, it handles the sometimes ugly task to convert between all these formats and provides some elementary operations (copying, scaling, alpha blending etc)

From the OpenQuicktime site, http://www.openquicktime.org: "OpenQuicktime aims to be a portable library for handling Apple's QuickTime(TM) popular media files on Unix-like environments. It is aim is to provide encoding, authoring and editing support as well as video playback." OpenQuicktime is currently able to decode as well as encode video and audio streams. The Video::OpenQuicktime library currently only supports extracting diagnostic information from Quicktime files, such as video dimensions, codecs used, and play length.

PhotoFilmStrip creates movies out of your pictures in just 3 steps. First select your photos, customize the motion path and render the video. There are several output possibilities for VCD, SVCD, DVD up to FULL-HD. The effect of the slideshow is known as "Ken Burns". Comments of the pictures are generated into a subtitle file. Furthermore an audio file can be specified to setup the background musice for the slide show.
