As we have now access to archived OSIRIS images and data from other instruments, I think that it's good idea to start up special topic for that.
Here are few results from the newly published data: Hi-Res crosseye stereo color image of Imhotep regio at resolution 0.5 m/pix. Anaglyph version: Global color image at 2.2 m/pix: -------------------- |

Thanks!
There is real color difference between neck area (Hapi and Seth regio) and head and body. Neck is more bluish. But global image is from uncalibrated data and global color differences are very subtle. Beyond that are source images clearly affected by lossy compression and this had major impact on quality of images (in this case). Losslessly compressed images had better quality and noise looks in them differently (as periodic stripes). This isn't problem for unenhanced images but only objects which have distinctly different color without enhancing are water ice boulders. Those are visible mostly on higher resolution images (there is whole icy boulder field in the crosseye/anaglyph stereo image). -------------------- |
