Delphi ASIO & VST Project

With these packages for Delphi the user can easily create VST plugins or ASIO applications within minutes. The included algorithms for filters and dynamics help to built effects without much knowledge of digital signal processing.

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]

JAITools

JAITools is a library for Java developers who work with raster images. It extends the Java Advanced Imaging (JAI) library, providing new image operators and utilities.

leptonica

Leptonica LibraryThe library supports many operations that are useful onDocument images Natural images Fundamental image processing and image analysis operationsRasterop (aka bitblt) Affine transforms (scaling, translation, rotation, shear) on images of arbitrary pixel depth Binary and grayscale ... [More] morphology, rank order filters, and convolution Seedfill and connected components Image transformations with changes in pixel depth, both at the same scale and with scale change Pixelwise masking, blending, enhancement, arithmetic ops, etc. Ancillary utilitiesI/O for standard image formats (jpg, png, tiff, bmp, pnm, gif, ps) Utilities to handle arrays of image-related data types (e.g., pixa, boxa, pta) Utilities for stacks, generic arrays, queues, heaps, lists; number and string arrays; etc. Examples of some applications enabled and implementedOctcube-based color quantization (w/ and w/out dithering) Modified median cut color quantization (w/ and w/out dithering) Skew determination of text images Segmentation of page images with mixed text and images jbig2 unsupervised classifier Border representations of 1 bit/pixel images and raster conversion for SVG Postscript wrapping (levels 1, 2) of images for device-independent output Connectivity-preserving thinning and thickening of 1 bit/pixel images Search for least-cost paths on binary and grayscale images Barcode reader for 1D barcodes (very early version as of 1.55) Implementation characteristicsEfficient: image data is packed binary (into 32-bit words); operations on 32-bit data whenever possible Simple: small number of data structures; simplest implementations provided that are efficient Consistent: data allocated on the heap with simple ownership rules; function names usually begin with primary data structure (e.g., pix) Robust: all ptr args checked; extensive use of accessors; exit not permitted Tested: thorough regression tests provided for most basic functions; valgrind tested Ansi C: automatically generated prototype header file Portable: endian-independent; builds in linux, osx, mingw, cygwin, windows Nearly thread-safe: no non-const global vars Documentation: large number of in-line comments; web pages for further background Examples: many programs provided to test and show usage of approx. 1600 functions in the library Open Source Projects that use Leptonicaphp (scripting language for dynamic web pages) tesseract (optical character recognition) jbig2enc (encodes multipage binary image documents with jbig2 compression) [Less]

zarzamora

Zarzamora Tools for Machine VisionDiverse tools are hosted here. All of them are small tools meant to make machine vision easier. Convolver BerryA tool to apply convolution filters for any image. Currently uses OpenCV. Very useful for teaching and for crafting kernels. QT OpenCV IplImage WidgetA ... [More] QT Widget for efficiently displaying an IplImage into a QT 4.x widget. Is directly based on QWidget, so it does not use any QLabel or QPixmaps, it paints directly onto a QWidget using a QPainter. If you just want to display an image is as easy as IplImage* img; ... image = new QOpenCVWidget; image.putImage(img);Get your fresh copy now from the downloads, or get the uber fresh by svn: svn checkout http://zarzamora.googlecode.com/svn/trunk/QOpenCV QOpenCV [Less]

pnnet

The project is aimed toward support of neural network topologies of any type. At the moment pann library is capable of running feedforward propagation and least mean square learning algorithm on any network. You construct network step by step and library can train it, visualize it in 3D(using Qt ... [More] OpenGL). All algorithms of propagation(feedforward and training) are done in parallel, depending on processor count or your settings. Library uses Boost and Qt4. All external dependencies are kept as small as possible. Now all you need for functioning is boost. Qt4 is optional and used only for small visualization utility - pann_viewer. There are also a lot of programs. Most interesting is face finder. It constructs Convolution neural networks and trains it to distinguish between face/not-face. Development platform: CMake, Linux, MS Windows External dependencies: boost thread, boost date-time(only on windows), boost serialization, pthread(only linux), boost MPI(optional), qt4 (optional) For more details look wiki and doxygen comments in source code :) Comments and questiones are much appreciated.

imgproc

just a collection of image processing classes. initially for actionscript.

VisiCode

VisiCode is an application to learn the algorithm of convolutional codes. The convolutional encoder is implemented as a shift register, the decoder as a trellis diagram which implements a maximum likelyhood decoder (MLD) with the viterbi algorithm. The application is in german only.

convoLV2

LV2 convolution plugin

gbmpl

This is a simple and highly readable image processing library written in C++ that supports 256-color gray-scale bitmaps. Features include rotation, convolution, edge detection, frequency-based filtering, blurring techniques, median filtering for noise removal etc. The library is growing very fast and more features will be added continuously.
