A free open source Java application created to help you apply watermarks to your pictures in order to protect them from unauthorized distribution. Different font, color, size and transparency texts or images can be added as a watermark. Batch processing is also provided.

Windows & Linux image processing tools. Supports multi-core, 8 to 64-bit resolutions for grey,RGB,HLS,CIE Lab and Bayer images. Handles dng,tiff,fits,jpg,j2k,png and raw file formats. eLynx lab is a GUI application based on wxWidgets & eLynx SDK.

Image Tools is a screen capture, file sharing and image processing tool. It features multi-threaded batch image resizing, conversion, cropping, flipping/rotating, watermarks, decolorizing (grayscale, negative, sepia), and optimizing. The BMP, GIF, TIFF, JPEG, PNG, and EMF image types are supported. It is compatible with Linux MONO (only for GNOME and Xfce). Multicore processing is supported to increase performance. The quality for output when optimizing is variable. Color channels can be filtered. An internal benchmarking tool is available. Indexed pixel format images can be processed. You can process your images, publish pieces of your screens, files and send links to everyone you want to share it.

TextureAtlas Toolbox is an all-in-one solution for working with texture atlases and sprite sheets. Extract sprites into organized frame collections and GIF/WebP/APNG animations, generate optimized atlases from individual frames, or convert between 15+ atlas formats. Perfect for game developers, modders, and anyone creating showcases of game sprites.

Tested on: Windows 7, Windows XP, Linux Ubuntu, Linux Mint.

Foresight is a LGPLed wrapper that currently brings together the Intel IPL, Intel OpenCV, ImageMagick, and the Matrox MIL. The ultimate goal is to provide a standard interface for any number of acquisition and image processing libraries.

"aura" tool is a desktop (X root window) background setter, making heavy accent on image processing and clever scaling (liquid rescale, solid margins cropping, labelling) capabilities.

AiGfxLab is a powerful open source image processing application for Windows. The plugin architecture permits both general-purpose and specialized processing, with an emphasis on intuitive GUI, numerical accuracy, maximal extensibility and customization.

Amoeba is an implemenatation of a research paper titled "Fast and Accurate Edge-Based Segmentation with No Contour Smoothing in 2-D Real Images" (IEEE tran on Image Processing, July 2000).This is a completed work, hence no promises for support ;)

Asido is a PHP (PHP4/PHP5) image processing solution, with "pluggable" drivers(adapters) for virtually any environment (GD2, Image Magick, etc). Asido does: various resize routines, watermark, rotation, copy images, cropping, grayscale, convert, etc.

bbips - Bash Batch Image Processing Scripts. A collection of bash scripts that use Imagemagick to "batch" process entire directories of images all at once. For use with Linux and Unix systems to batch process *.jpg image files from the bash shell.

The Common OCR Service Interface. COSI is an API that allows developpers to easily bring OCR (Optical Character Recognition) capabilities to image processing applications. COSI supports existing OCR tools such as Tesseract, GOCR or GNU Ocrad.

Batch script for images (manga/comics) preparation to be comfortably viewed on COWON A3 PMP. It also can be used in conjunction with xps2img (http://xps2img.sf.net) to do PDF conversion for reading on A3.
