Mitsuba is a research-oriented rendering system in the style of PBRT, from which it derives much inspiration. It is written in portable C++, implements unbiased as well as biased techniques, and contains heavy optimizations targeted towards current CPU architectures. Mitsuba is extremely modular: it consists of a small set of core libraries and over 100 different plugins that implement functionality ranging from materials and light sources to complete rendering algorithms. In comparison to other open source renderers, Mitsuba places a strong emphasis on experimental rendering techniques, such as path-based formulations of Metropolis Light Transport and volumetric modeling approaches. Thus, it may be of genuine interest to those who would like to experiment with such techniques that haven't yet found their way into mainstream renderers, and it also provides a solid foundation for research in this domain. Mitsuba comes with a command-line interface as well as a graphical frontend to interactively explore scenes. While navigating, a rough preview is shown that becomes increasingly accurate as soon as all movements are stopped. Once a viewpoint has been chosen, a wide range of rendering techniques can be used to generate images, and their parameters can be tuned from within the program.

Mscgen is a small program that parses Message Sequence Chart descriptions and produces PNG, SVG, EPS or server side image maps (ismaps) as the output.

OpenColorIO (OCIO) is a complete color management solution geared towards motion picture production with an emphasis on visual effects and computer animation.

Deegree iGeoPortal is the web-based portal framework of deegree. It offers visualization of geodata through a standard web browser like Mozilla, Firefox or MSIE.

Captcha::reCAPTCHA::Mailhide - A Perl implementation of the reCAPTCHA Mailhide API reCAPTCHA is a hybrid mechanical turk and captcha that allows visitors who complete the captcha to assist in the digitization of books. reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly. http://recaptcha.net/learnmore.html

GD::Barcode is a subclass of GD and allows you to create barcode image with GD. This module based on "Generate Barcode Ver 1.02 By Shisei Hanai 97/08/22".

Image::Grab is a simple way to get images with URLs that are either not predictable or are "hidden" by some method.

The Utah Raster toolkit is a collection of programs and C routines for dealing with raster images commonly encountered in computer graphics. It provides the following major functions: * A device and system independent image format for storing images and information about them. Called the RLE format, it uses run length encoding to reduce storage space for most images. * A library of C routines for reading, writing and manipulating images stored in the RLE format. * A collections of programs for manipulating and displaying RLE images.

A set of command line (and one GUI) programs for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames.

ppsei (PPS Extract Images) is a simple command line program, which tries to extract images from Microsoft PowerPoint documents (PPS/PPT).
