There's been discussion elsewhere on the forum about how to demosaic images that come down as raw pixel values from cameras with Bayer filters, but I have not been able to do this myself and am looking for some help. What do you folks recommend to demosaic images? I'm a Windows user...

In this post Damia recommended ImageJ with the Debayer plugin. I downloaded ImageJ (now Fiji) from here and the Debayer plugin from here as well as the PDS Reader plugin from here. Trying the Debayer plugin on a raw MSL image, the following error appeared in the console, and I'm not sure what to do to solve the problem; can anybody help?

Please remove or make sure it appears in the correct subdirectory of the classpath.

Yes! Hadn't tested it myself, so it was somewhat of a stab in the dark ... but I'm glad it worked! cool.gif
