Scan documents (with SANE) or import ODF documents, assign tags. Use openDIAS to store all our letters, bills, statements, etc in a convenient, safe and easily retrievable way.

opengallery takes a dirtree of image files and creates a web site with frames, thumbnails, subdirectory navigation and optional javascript highlighting.

openlpr is a open source project to implement license plate recognition in Win32 and Linux platform. It will provide the basic image processing to locate plate and character split and a neural network design to recognize character.

Linux drivers for Rolsen MNT-101 (Pegasus Mobile NoteTaker) digital pen.

osgGtk is a library of C based Gtk+ and C++ based Gtk-- widgets to support OpenSceneGraph (OSG) applications. The library also includes several example applications such as osgviewerGtk and osgviewerGtkmm.

pcdtoppm is a mod­i­fi­ca­tion of the pcd­to­jpeg Pho­to CD con­ver­sion util­i­ty (http://pcdtojpeg.sourceforge.net) that out­puts PPM rather than JPEG.

A unified photo collection manager for large photo archives. Maintains a database of photos in a category tree structure. Supports automatic generation/maintenance of thumbnail images, HTML archive pages, and slideshows. Interfaces with digital cameras.

Perlin noise is a form of noise with local coherence. It's used in creating all kinds of graphics, from wood efffects to marble. The editor lets you create an image with Perlin noise interactively, and save it as a gif. You can change the noise parameters, and you can edit the palette, either loading it from a gif, or using the palette editor (right click to open the color picker, left click to move the two selection points about). There's also a handy tool for tuning the palette as the image adjusts (drag on the red circle to adjust, the black circles to move the edit range).

This tool tries to find a suitable clipping border for a series of gray images. It is very useful to automatically extract clipping values for transcoding a movie if the source frame is encoded with black bars.

A multiplatform picture composer (average, brightest, darkest, weighted etc. as you know that from image editors)

A quick image scanner and parser to recursively search and find images based on usesr specified criteria(such as resolution on both image axis) and supporting a large number of graphic formats.

pixelite provides a complete build environment (cross toolchain) for microcontrollers including a c library (newlib libc) and makefile framework: Atmel ARM, AVR, Renesas H8, SH, RX, NEC v850. Cortex M3 should also work. GDB support stubs are planned.

This is a lightweight and fast library for reading and writing any PNM file - PBM, PGM and PPM, up to 16 bits per sample, in ascii/binary format. Library contains also a Python bindings - module pixfiles with PixFile class.

Pixia a tiny memory pixel/bitmap operation library which presents platform-independent functions such like blit/scaling/rotation etc.

SWI-Prolog interface to ImageMagick graphics processing library

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.

Extract the colour table from a paletted (indexed) png image and write it to stdout in decimal or hexadecimal text.

Automatically stitch, transform, blend and crop pnm images together to form a panorama. Support low overlap, high resolution Digital Camera images primarily with a focus on heuristics to improve the quality of the match.

GTK+/X provides a much-needed solution for smaller systems and embedded devices.On client side XCB exchanges Xlib's numerous features for smaller size and enhanced performance.In GTK-XCB project,we intend to port Gtk to XCB for increased performance.

pyFormex is a program for generating, transforming and manipulating large geometrical models of 3D structures by sequences of mathematical operations.

pymesh will be a Python interface for Triangle (2D) and Tetgen (3D) mesh generators.

This program will traverse a directory tree, processing jpeg image files to produce neat and easily navigatable HTML image galleries. qgallery will automatically generate thumbnails, ando can also ptionally downsize images to ensure that they fit the
