Thanks Manuel - looking forward to more results.

Its improving

Fantastic!

Its improving 

Wonderful...!

What have you done ?  What did you change?

[Mfranquelo]

2 more cameras on the way for the ears.

- Ive made the light more diffuse, and i smoothed the mesh in Meshlab, and finally ive added a displacement map on zbrush with a wavelength decompose filter from GIMP.

- Mesoscopic high pass filter from disney research lab is so amazing (i hope one day i can get it on my hands)

[Mfranquelo]

Heres one with texture map and no displacement map.

[Exhale]

yes, exactly improving...

Did you do Photoshop - Enhancing Photos with High Pass Filter ?  if not, you may give a go.

What smoothing have you applied on Meshlab from filters section? Why not Zbrush smoothing?

Thx

Hello exhale

Im using this equivalent to photoshops high pass filter http://registry.gimp.org/node/11742 it works a little bit better from my tests.

I?ve applied "two step" smoothing filter, however it doesnt work as i?d like to, details arent preserved in the way i wanted. I might have a custom made bilateral denoise filter on the upcoming months... im not counting on it though. - Im very supprissed to not be able to find any software that have this kind of filter for 3d mesh... not even polyworks.

- The problem now with high pass filter is that my lights are moving relative to the subject so dark / light information is nowhere near accurate. I will change this on the following weeks.

[Exhale]

have a look at this one, pay attention also boosting.. that's cool...

there is no program lunched for this research  

[Mfranquelo]

Wow,

I know  , i?ve been researching code libraries and noone of the most used ones have implemented this smoothing algorithm.. most of them have old smoothing algorithms like laplacian, not even the bilateral denoise.  Agisoft, you need to implement this algorithm!

Have you improved your technic ? Is there less noise ?
Would you interested in uploading some photos
By the way, what have you done about the zbrush work flow?
Can you upload some compression photos please.
 Good luck,
Thx

[Mfranquelo]

I?ve been away some time for vacations, im back now!

- Im adding two more cameras for my system so i?ll upload results this week or the next one. Noise should be less and it will allow me to record the ears as well.
- Im about to watch and study the videos that wishgranter shared so i will post results as well.

- Im routing a section of a face scan with 100 microns resolution on X , Y , Z axis.
I will post images of the physical object.

Nice rig !
On your installation mosaic picture it seems that the scanned person is laying on the floor which gives not very flatering faces with the fleshy parts moving backwards
couldn't you install it on the wall instead ?
