Open Source Unix Shell Image Processing Software

"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.

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.

XMIPP is an image processing suite for 3D-reconstruction of biological specimens from transmission electron microscopy data. NOTE that stable releases (including binaries) are longer stored at Sourceforge, but are available at http://xmipp.cnb.csic.es

PicBook automatically produces a photo album in HTML format of your images. It come with automatic image processing, slideshow, transition effects and other nifty stuff. It is easy to customise due to a configuration file and HTML-templates.

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.

openSkyMatch is a collection of Linux shell and Python scripts designed for the OpenScience Observatories program. It automates the identification and matching of detected celestial objects in locally captured FITS images with entries in large-scale sky catalogs, notably Pan-STARRS1 DR2 (II/389/ps1_dr2). The toolkit supports data preprocessing, coordinate correlation, and catalog-based validation of astronomical detections. All tools are open-source and optimized for reproducibility and transparency in citizen science astronomy.
