numa numa is a file recovery tool for the ext3/ext2 file system. It recovers deleted GIF/JPEG files of less than 48kb. OpenVIDIA The OpenVIDIA project implements computer vision algorithms on computer graphics hardware, using OpenGL and Cg. The project provides useful example programs which run real time computer vision algorithms on single or parallel graphics processing units(GPU). pecomato PECoMaTo stands for Picture-Embedded COntents MAnipulation TOol. It is basically designed to display any kind of information embedded in picture files, as well as checking, filtering, extracting, removing, adding and fixing such information. In other words, it's a metadata processor. Perceptual Image Diff Perceptual Image Diff is a command line utility that tells you if two similar images are different from the point of view of a theoretical human observer. It's useful for running automated regression testing on images that are perceptually identical but have minor pixel noise from different random number generators or small changes to algorithms. Pinta Pinta is an extremely versatile, extensible, self-learning image classification program. It uses texture and color analysis and neural network techniques to automatically learn differences in images. pLoader pLoader is software dedicated to photo preparation and transfer to your Piwigo installation. pngcheck pngcheck verifies the integrity of PNG files (by checking the internal 32-bit CRCs or checksums) and optionally dumps almost all of the chunk-level information in the image in human-readable form. pngslice The pngslice utility is a tool for creating ragged images in HTML: Eric Meyer's ragged floats. The idea is to slice the image into thin strips that are trimmed and stacked vertically. The program produces the trimmed PNG slices and a fragment of HTML to include them. PNGwriter PNGwriter allows you to plot to a 16-bit PNG file, saving it directly to disk. Plotting is as easy as specifying the red, green, and blue values and the x, y coordinates of the pixel. pnmcurve pnmcurve is a command line tool that applies tone curves to pnm images. Curves are specified as a set of control points of a cubic spline. pnmcurve applies the resulting spline curve to the pnm image read from stdin and writes the resulting image to stdout. Command line switches allow the user to apply the curve only to selected color channels. ppminfo ppminfo shows details of a ppm file on the console, displaying the resolution and some statistics. ppmtofb lppmtofb lets you display netpbm-format graphics on framebuffer consoles. ppsei ppsei (PPS Extract Images) is a simple command line program, which tries to extract images from Microsoft PowerPoint documents (PPS/PPT). Qlickr Qlickr is a Qt-based application for uploading photos to Flickr. Rapid Photo Downloader Rapid Photo Downloader is written by a photographer for professional and amateur photographers. Its goal is to be the best photo downloader for the Linux Desktop. recoverjpeg recoverjpeg tries to recover JFIF (JPEG) pictures from a peripheral. This may be useful if you mistakenly overwrite a partition or if a device such as a digital camera memory card is bogus. RenRot Renrot renames files according the DateTimeOriginal and FileModifyDate EXIF tags, if they exist. Otherwise, the name will be set according to the current timestamp. Additionally, it rotates files and their thumbnails, accordingly Orientation EXIF tag. The script can also put commentary into the Commentary and UserComment tags. Personal details can be specified via XMP tags defined in a configuration file. saltshaker saltshaker is a Python script for shaking things in the open source Blender 3d system. A lot of information/comments are included for budding Blender Python script writers. Shoebot Shoebot is a pure Python graphics robot: it takes a Python script as input, which describes a drawing process, and outputs a graphic in a common open standard format (SVG, PDF, PostScript, or PNG). Shoebox Shoebox is a pure Python version/rewrite of Nodebox. It can read scripts in the Nodebox language and output images in SVG, PostScript, PDF or PNG format using the Cairo rendering engine. Comparing to graphics coding alternatives like Nodebox and Processing, Shoebox is lighter and more flexible thanks to not depending on an interface engine for rendering, thus making it potentially suitable for CPU-conscious uses like server applications. Unlike Processing and Nodebox though, Shoebox can only output still images for the time being. It can be run stand-alone on a shell or as part of a Python program. SmartPainter SmartPainter generates images for the user to decide if they are pleasing to their eye. Then, once the images have been rated, more random images will be generated similar to the best looking ones. SnapMatcher SnapMatcher is an application intended for photographers, artists, or image packrats who have very large collections of digital images, some of which may be duplicates or near duplicates. By identifying images across multiple formats with the ability to filter out minor edits such as changes to contrast, brightness, color balance, resizing, or even the addition of text or borders SnapMatcher can be a valuable tool in organizing culling unwieldy collections. Sortdemo Sortdemo generates sequences of image files (GIF or PNG) to visualize the steps of sorting algorithms. Stegdetect Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting severval different steganographic methods to embed hidden information in JPEG images. Structure Synth Structure Synth is a cross-platform application for generating 3D structures by specifying a design grammar. Even simple systems may generate surprising and complex structures TarTheft TarThef is a PACS (picture archive communication system). It works with the version-control system 'subversion'. It "steals" large files (e.g. pictures that can be +100MB per piece) from a subversion repository, puts them on tape, and then marks those revisions. Then, the repository is stripped to make the disk-based repository smaller again. TarTheft provides long-term archiving, making it possible to link disk-based files with their tape backups. tintii tintii cleverly separates the colour profile of a photo into a handful of major hues. Select which colours to keep, and the rest becomes black & white. TOIlet The TOIlet project attempts to create a free replacement for the FIGlet utility. TOIlet stands for ?The Other Implementation?s letters?, coined after FIGlet?s ?Frank, Ian and Glen?s letters?. ViewMe ViewMe is for opening files that need to be viewed with other viewers. It supports URLs, commands, or any other file type. It was largely inspired by LHA but it has far more features. vinetto Vinetto is intended to extract thumbnails and associated metadata from the Thumbs.db files created by the Windows Explorer. wavextract wavextract is a program for extracting embedded audio data from JPEG images. It is useful if you have a digital camera that can record audio notes and embed them in photos (e.g. HP, Kodak, Canon, Fujifilm, etc.)
