SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.
Swiss army knife of image processing
GraphicsMagick provides a set of commandline tools and programming APIs for manipulating, editing, and converting raster and vector images. It is derived from ImageMagick, with the objective of providing better stability and performance than ImageMagick while retaining the original MIT/X11 license.
pfstools - a set of programs for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames. pfscalibration - photometric calibration of cameras and HDR images from multiple exposures. pfstmo - tone mapping operators.
A modified pngnq: convert png images to 256 colours.
pngnq-s9 is a modified version of pngnq, the neural network colour quantizer for png images. Like pngnq, pngnq-s9 takes a full 32 bit RGBA png image, selects a palette of up to 256 colours, and then redraws the image in 8 bit indexed mode. The resulting image can be up to 70% smaller than the original. pngnq-s9 adds several new options to pngnq including the ability to augment a user-supplied palette, the ability to quantize in the YUV colour space, and the ability to give more or less weight to specific colour components when quantizing. The program also includes a few bug fixes relative to the most recent version of pngnq. The .tar.gz files have been known to compile on Unix type systems, including Cygwin. The only external dependencies are libpng and zlib. For Windows users, we have a 32 bit binary, in pngnq-s9-2.0.2.zip, that should run as is on most modern Windows machines.
AuctionGallery is a terminal script that creates picture galleries and HTML descriptions for the purpose of putting them into auctions like eBay or Yahoo! Auctions. It is aimed at power-sellers who need an efficient way of generating auction descriptons.
svgconv is a content tool to convert SVG paths into a C format that can be easily used with OpenVG.
Goki check aims to detect context from an image in deterministic way.
From 3D model, goki check matches 2D image.

A free open-source paint/image manipulation program
Paintbear is a free open-source Paint Program and Image Manipulation Program for Windows based on the .NET Framework(version4). Works on Linux,too ! With Wine or Mono Framework !
A media management solution for digital photographers who have to manage large amounts of digital media. Its strength is its native support for RAW images (Nikon, Canon, etc.), version control, team functionality, speed, and cross-platform compatibility.
hdrff is a modular shell script (bash) for automatic processing of HDR image-sequences. It supports the complete workflow from downloading the images to the harddisk, aligning, HDR-creation and tonemapping.
Convert jpeg(exif/jfif)/mpo/jps image to/from xml
This is a set of command line tools that are useful for editing image metadata. Currently it contains the following tools: * image2xml * xml2image * mpo2jps Currently supported file formats are: * jpeg (jfif or exif) * mpo * jps. These tools are mostly useful for editing metadata. image2xml can also generate a .h header file with the offsets of different metadata in the binary file. This could be used in small devices that generate jpeg/mpo/jps images where metadata construction from scratch is not required.
libGDISVG is the first cross-platform library that implements parts of the MS Windows API to generate Scalable Vector Graphics (SVG). The library is an independent variant of libEMF.
