Open Source C Algorithms

libmng -THE reference library for reading, displaying, writing and examining Multiple-Image Network Graphics. MNG is the animation extension to the popular PNG image-format.

minidjvu is a DjVu encoder for black-and-white images.

darknocK detects edges in images. It is using Artificial Neural Networks to enchance the results of standard algorithms.

CRCLIB is a small library of CRC calculations which can be used in other programs. Because CRC check is often used by binary communication protocols, it is made as simple as it can be, built into library so that it could be used regardless of language of application code. Written in plain C, built as dll and static library, and also contains C/C++ import header, C# wrapper and .NET project for MS SQL Server assembly. Supports CRC16 (including MODBUS) and CRC32.

CthughaNix is the reincarnation of Cthugha-L, a Linux port of one of the first audio visualization software packages, known as "An Oscilloscope On Acid".

Ertha is an open source GIS whose main focus is to guarantee easy extensibility and straightforward integration of custom modules. It provides basic geographic rendering and topologic analysis and exposes the main data structures loaded from shapefiles.

The Local Binary Pattern (LBP) is a texture operator that is used in several different computer vision applications and implemented in a variety of platforms. When selecting a suitable LBP implementation platform, the specific application and its requirements in terms of performance, size, energy efficiency, cost and developing time has to be carefully considered. This is a software toolbox that collects software implementations of the Local Binary Pattern operator in several platforms: - OpenCL for CPU & GPU - OpenCL for GPU (branchless) - C code optimized for ARM - OpenGL ES 2.0 shaders mobile GPUs - C code for TI C64x DSP core (branchless) - C code for TTA processor synthesis If you use the code somewhere, please cite: Bordallo López M., Nieto A., Boutellier J., Hannuksela J., and Silvén O.

Legacy Film to DVD Project

A test suite and benchmark for exact Euclidean distance transform algorithms used in Image Processing and computational geometry. It evaluates the exactness and speed of algorithms for a large number of test cases. Results can be visualized in Scilab.

UIMP(Unified Image Manipulation Program) is an OS independent Image Processing system, which provides over 1000 algorithms and supports web online, console and GUI program.

This is the Utah Raster Toolkit distribution version 3.0 of June, 1990. ~~~ librle.a, image.rle file type support, animation, rletogif, converters, many utilities. RLE format supports a great number of raw inner formats for applications to use, known together as .rle (ie, "stored windowing") ~~~ 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. License: says it's "GNU like" in the license.

Library for embedded real-time Digital Signal Processing / Digital Image Processing algorithms, XDAIS compliant.

A new AAC encoder(different with FAAC, nero aac or qtaac), very good quality. support Linux and Windows platform. Support 6 speed level, default is 3. level 3 can supply good quality of the AAC file, if you want the best quality, use level 1, but the speed is slow.

Library for calculating fields of view and lighting on low resolution rasters, suitable for roguelike games.

A library written in C for lossy image compression. Library libopen/format OPEN supports two methods of compression - discrete cosine transform (used in JPEG) and discrete wavelet transform (used in JPEG2000).

The algorithm will carving zeros in an integer array initialized to "1". Data can be recorded in a simple way.

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.

It software decodes EAN-13 bar code picture by image processing. And a GUI is ship together with it, which can take picture from web camera. So the only thing you need to recognise barcode apart you computer is a webcam.

x86mph is an optimized library with vector, matrix, and vertex helpers (including an own TnL) It also contains memory helpers, and other stuff such as image processing (color inverting, changing bpp) taking advantage of x86's 3DNow!, MMX, and SSE
