SLEEF stands for SIMD Library for Evaluating Elementary Functions. SLEEF implements vectorized versions of all C99 math functions, that utilize SIMD instructions of modern processors to make computation more efficient. The library also includes vectorized DFT subroutines.

A header-only, C/C++ library that lets you transform an input image or video frame into printable ASCII characters in real-time using a single decision tree. ASCII Art is a single header, C/C++ library developed by PixLab and based on the work of Nenad Markus that let you transform an input image or video frame into printable ASCII characters at real-time using a single decision tree.

XMLStarlet is a set of command line utilities (tools) to transform, query, validate, and edit XML documents and files using simple set of shell commands in similar way it is done for text files with UNIX grep, sed, awk, diff, patch, join, etc utilities.

Rbmake is both a library of routines and a set of command-line utilities that enables a user to transform content into Rocket Ebook format (.rb) files and back again (unencrypted files only). Compatible with the Rocket Ebook and the REB 1100.

...High speed and small memory usage is its main concern. It implements a subset of JPEG standard. Now the code contains JPEG decoder so if you decided to use nonstandard transform or entropy coding in encoder you still will be able to decode bitstream (provided that you keep the decoder in sync of course). Release 1.1 source code and Windows executables are on the download page. For the latest release code look into the repository in 'release-1-0' branch. The SSE2 inplementation is present in 'simd.0' branch in the repository.

...osm_cut: create rectangular extracts tr_view: view tool for trafalgar files, including fast osmtoolz import filter, GPX an KML track import (see screenshots) There is a small script included which helps to transform from *.bz2 to *.gz using a named pipe (seems not to work for cygwin)

BEMAP (BEnchMarks for Automatic Parallelizer) is a benchmark used to measure performance for an automatic parallelizer. All OpenCL code benchmarks covered in this project are done step-by-step along with hand-tunning. Each tuning step executional time are measured in details with a comprehensive user interface and help option. The exact implementation in native code (C++) is also provided in each project folder for reference. By using these benchmarks, one may analyze: 1. How to...

Tiny-DSP library contains c sources of a fast, tiny, portable and generic FFT (Fast Fourier transform) and inverse FFT. Supported are all power of two sizes (like 2,4,8,16,32,...) for one and two dimensional floating point arrays.

Transform USB keyboard events into X11 keyboard events. Transformation is scriptable using ruby, allowing for complex keyboard interfaces not covered by the standard X11 keymap. Think of it as autohotkey for X11.

Foad is an open source software which receive an EKG Signal from scanner, WFDB database or heart sensors. Finding patient disease started by taking Fourier transform (FFT) from input signal and extract a single cycle. Based on some heuristic algorithm the most important feature like P , Q , R , S , T captured and feed to trained neural network. and so the final decision made by CNN library. As mentioned before this software also capable do some image processing on scanned paper to lower the final costs.

Parse software messages and transform them into actions. LazyBat has a command line utility which can transform input data, and also a parser generator for C/C++. LazyBat doesn't support recursive parsing, but rather focuses on common parsing jobs.

Continuous wavelet transform library

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.

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).

A Tcl library extension for managing virtually any kind of images. It can load, save, display, transform images in a very simple and fast way. Supports the following image types: BMP,GIF,ICO,TGA,PCX,WBMP,WMF,PNM,PPM,PGM,RAS,JPEG-2000,JBIG,TIFF,MNG,PNG,JP

The Arbitrarily-Decomposed MPI FFT library is a C subroutine library for the computation of the multidimensional Fast Fourier Transform (FFT) of a distributed grid using the Message-Passing Interface (MPI).

This is a research project to test GPU (OpenCL) usability for image compression. Jpeg format is chosen because it is relatively simple and I am familiar with it. 2013-01-22: For now only pixel conversion and DCT transform is done with OpenCL, entropy coding is done with CPU in one thread. Unfortunately this implementation is no match for even one threaded SSE2 jpeg encoder, too much data goes through PCIe. Look at "Debunking the 100X GPU vs. CPU Myth: An Evaluation of Throughput Computing on CPU and GPU" paper by Victor W Lee, Changkyu Kim, Jatin Chhugani, Michael Deisher, Daehyun Kim, Anthony D. ...
