Cairo is a vector graphics library with cross-device output
support. Currently supported output targets include the X Window
System and in-memory image buffers. PostScript and PDF file output is
planned. Cairo is designed to produce identical output on all output
media while taking advantage of display hardware acceleration when
available (eg. through the X Render Extension).
Cairo provides a stateful user-level API with capabilities similar to
the PDF 1.4 imaging model. Cairo provides operations including stroking
and filling Bezier cubic splines, transforming and compositing translucent
images, and antialiased text rendering.
Context Free Design Grammar compiler.
About CFDG:
Chris Coyne created a small language for design grammars called CFDG.
These grammars are sets of non-deterministic rules to produce images.
The images are surprisingly beautiful, often from very simple grammars.
Context Free is a full graphical environment for editing, rendering,
and exploring CFDG design grammars.
Features:
* Simultaneously available for Macintosh, Windows and Posix/Unix.
* Progressive image update: watch it generate
* Save generated images in PNG or SVG format.
* Produce animations
* Edit grammars and re-render easily.
* Render very large images (as large as 100 Mega-pixels).
* Can handle generated images with millions of shapes.
* Carefully tuned graphics rendering
* Many built-in examples
* Automatic checking for updates (Mac only).
* It's free, as in beer and as in speech.
ChBg is used for changing desktop background pictures with some period.
Can also be used as a xscreensaver hack.
CinePaint is a free open source painting and image retouching program
designed to work best with 35mm film and other high resolution high
dynamic range images. It is the most popular open source tool in
the motion picture industry -- used in 2 Fast 2 Furious, Scooby-Doo,
Harry Potter, Stuart Little and other feature films. CinePaint is
used for painting of background mattes and for frame-by-frame
retouching of movies.
Clutter-GTK is a library providing facilities to integrate Clutter into GTK+
applications. It provides a GTK+ widget, GtkClutterEmbed, for embedding the
default ClutterStage into any GtkContainer.
Clutter it an open source software library for creating fast, visually
rich and animated graphical user interfaces.

Gwenview is a fast and easy to use image viewer for KDE.
Features:
- Supports simple image manipulations: rotate, mirror, flip, and resize.
- Supports basic file management actions such as copy, move, delete,
and others.
- Functions both as a standalone application and an embedded viewer
in the Konqueror web browser.
- Can be extended using KIPI plugins.
Ipe is a drawing editor for creating figures in PDF or (encapsulated)
Postscript format. It supports making small figures for inclusion
into LaTeX-documents as well as making multi-page PDF presentations
that can be shown on-line with Acrobat Reader.
OpenCV (Open Source Computer Vision Library) is an open source
computer vision and machine learning software library. OpenCV was
built to provide a common infrastructure for computer vision
applications and to accelerate the use of machine perception in the
commercial products. Being a BSD-licensed product, OpenCV makes it
easy for businesses to utilize and modify the code.
The library has more than 2500 optimized algorithms, which includes
a comprehensive set of both classic and state-of-the-art computer
vision and machine learning algorithms. These algorithms can be
used to detect and recognize faces, identify objects, classify human
actions in videos, track camera movements, track moving objects,
extract 3D models of objects, produce 3D point clouds from stereo
cameras, stitch images together to produce a high resolution image
of an entire scene, find similar images from an image database,
remove red eyes from images taken using flash, follow eye movements,
recognize scenery and establish markers to overlay it with augmented
reality, etc.
