KARWY tool for ARW2 Artifact Repair

KARWY, the free software tool I've been building for credible repair of Sony ARW2 raw artifacts , is now live as a Beta-test version. The current version is run via a WWW form interface, so you don't need to install anything to use it. The home page for this research project is:

http://aggregate.org/DIT/KARWY/

Rather than posting repair examples, I encourage you to try your own -- and please use the rating and comment mechanism in the KARWY server to help me improve the performance of future versions of KARWY.

The tool works only on Sony ARW2 raw files to produce DNG raw files. Sony camera models producing ARW2 files include:

• Full Frame E-mount: NEX-VG900, A7, A7R, A7S, A7II, and A7RII
• APS-C E-mount: NEX 3, 5, 5N, 5R, 5T, 6, 7, C3, F3, VG20, and VG30, and ILCE 3000, 3500, 5000, 5100, 6000, and QX1
• A-mount: DSLR A450, A500, A550, A560, A580, A700, A850, and A900, and SLT A33, A35, A37, A55, A57, A58, A65, A77, and A99, and ILCA-77M2
• Cyber-shot: DSC RX100, RX100M2, RX100M3, RX100M4, RX10, RX10M2, and RX1

It is quite rare that ARW2 artifacts are visible in well-exposed, normally-processed, images. It probably isn't worthwhile running images that look OK through KARWY because it takes minutes to upload, process, and download a single image. However, if you've got some problem images, give it a try -- it's doing a really good job on all my test images.
