This is the homepage for the open source Seamstress seam carving library and Arachne, the seam carving program written to demonstrate the library. Seam carving is a technique developed by Shai Avidan and Ariel Shamir for resizing images by removing the boring bits.
A gallery of images made by sticking random toys into a radiograph.
A website that does online error level analysis of images (either linked or uploaded) to help determine whether or not they've been edited, and if so which bits were changed. Error level analysis is a technique in which the error level potentials of image files are mapped with algorithms developed and published by Dr. Neil Krawetz. Alterations tend to show up as having higher error potentials than the unmodified parts of the image (which have probably been saved a few times, and thus noise has crept in).
