GIMP

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring. It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch ... [More] processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted. GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X. [Less]

ImageMagick

ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale ... [More] , shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may freely use, copy, modify, and distribute in both open and proprietary applications. [Less]

grafx2

GrafX2 is a bitmap paint program that allows you to draw in more than 60 video resolutions including most of the standard Amiga resolutions : 320x200, 320x256, 320x512, 640x256, 640x512, etc. It was written to run under DOS, but the code you'll find here was modified to use SDL and modern ... [More] operating systems. This program is dedicated to everybody who knows what a single pixel is. Its layout is not very different from the famous Deluxe Paint or Brilliance, so it will be quite easy to handle it if you know at least one of these programs. If you aren't used to the art of drawing with up to 256 colors, it will be a little more difficult for you, but you should give it a try (or more, because most of the power of this program won't show up on the first try).

Verse

Verse is a network protocol that lets multiple applications act together as one large application by sharing data over a network. If one application makes a change to shared data, the change is distributed instantly to all the other interested clients.

Teem

Teem is a coordinated set of ANSI C libraries for manipulation, measurement, and visualization of structured scientific data. Includes N-dimensional image I/O and processing, volume rendering, diffusion tensor processing, ray tracing, PostScript rendering, and more. Teem includes command-line tools ... [More] that permit the library functions to be quickly applied to files and streams, without having to write any code. [Less]

V4l2capture

V4l2capture is a CLI software to grab images from a v4l2 image device.

NiftyReg

This project, developed at University College London, contains programs to perform rigid, affine and non-linear registration of nifti or analyse images. Two versions of the algorithms are included, a CPU- and a GPU- (using CUDA) based implementation.

libsquish

squishNewsWe've moved! So far there have been just a few minor edits since version 1.10, check the issues for the planned changes. FeaturesThe squish library (abbreviated to libsquish) is an open source DXT compression library written in C++ with the following features: Supports the DXT1 ... [More] , DXT3 and DXT5 formats. Optimised for both SSE and Altivec SIMD instruction sets. Builds on multiple platforms (x86 and PPC tested). Very simple interface. A description of the algorithms used to perform the compression can be found on my blog. Note that the cluster fit algorithm in squish now forms the core DXT compression algorithm for the NVIDIA Texture Tools. NVIDIA have been kind enough to allow implementation improvements to be refactored back into the library. Example UsageSee squish.h in the distribution for the documentation. The library has only two functions, one to compress a block of 4x4 pixels and one to decompress. The following program will compress then decompress a single 4x4 DXT block: #include int main() { squish::u8 pixels[16*4]; // 16 pixels of input squish::u8 block[8]; // 8 bytes of output /* write some pixel data */ // compress the 4x4 block using DXT1 compression squish::Compress( pixels, block, squish::kDxt1 ); // decompress the 4x4 block using DXT1 compression squish::Decompress( pixels, block, squish::kDxt1 ); }A wrapper API is also included to compress entire images in a single call. In addition, there is an example program provided with the library that shows how to use the squish library to compress and decompress between PNG and DXT format images. ContributorsThe squish library was originally written by: Simon Brown The following people have made significant contributions to the squish library: Ignacio Castaño (NVIDIA) AlternativesIt turns out that there are other open source DXT compression implementations out there on the interweb. Here is a list of the currently known competition: Jason Dorie's image library: ImageLib Mesa S3TC compression library: libtxc_dxtn I haven't had the time yet to do any comparisons between these libraries and squish. If anyone has then please let me know! [Less]

Salasaga

An Integrated Development Environment for producing presentation and simulation based eLearning (as Flash), similar to Macromedia Captivate. Licensed under the LGPLv3.

webcam-capture

WebCamCapture is a simple C# library for capturing still images from a Webcam. It works using the Video for Windows API and as such should work with virtually all webcams. It allows for both showing a video preview and simply taking pictures. In addition, it contains a simple "camera" ... [More] form so taking a picture is as simple as the click of a button and 2 lines of code. Right now only still image support is included, but in the future, video support may be included as well. Feel free to participate and help this happen. [Less]
