Superimposition of a graphic (jpeg) onto an anatomical image
Posted: Thu Sep 30, 2004 8:46 am
Hi,
i was very impressed by the "Mona-Lisa" on an anatomical brain (brainvisa.info/ museum.html). So i tried hard to achieve a comparable result with brainvisa/anatomist. I got an anatomical T1-Scan of my brain and made a mesh out of it. But now I fail to put a texture on this mesh. I really have no idea how to extract a texture out of a graphic (e.g. a jpeg). Maybe i got a wrong idea about this procedure. My questions are:
1) is it possible to extract a texture out of a graphic (e.g. jpeg)?;
2) how was it possible to put the "Mona-Lisa" onto an anatomical brain?;
3) if i got t-values in a datafile (eeg-data) and want to superimpose them on an anatomical brain - what headerfile do i need? What has to be declared in this headerfile (it looks so easy on the brainvisa homepage - but i guess there is no information on the page, how a header should look like or how "erp"-data should be structured).
I guess that my questions are maybe naive or trivial for expert users but be sure: i tried hard and getting crazy...
