comment Filter bright dots from the gradient of the image
I dont have an image without any dots, may be in future, If I want to just plot Intensity versus pixel corrdinates, is there any example I can do that in mathematica.

comment How to make 3d solid volume from set of images
I guess not, I am not sure if the final volume is just a isosurface or it is solid volume, can I save it as solid geometry. thanks for the input.

comment Calculating morphometric properties
@belisarius: That question was for 2d image, which had center line in the image. This question have 3d geometry and it doesnt have flat plane 2d image, I think this is entirely a different problem.

@belisarius, I guess tetgenconvexhull calculates polygondata from data point itself, see updated question. hope I was able to explain the question

comment How to process .vtk file
@ruebenko I was trying to export above Graphics3d into .vtk format, and then import as .vtk file, I am missing polygondata, as i understand those are just data points, is any way I can get polygondata of those points without using convex hull.

comment Construct a simple mesh or tetrahedral mesh from 3D image surface
I will try first to smooth the 3d graphics/image and re-post the question, that might help. I wanted to try tetgen.

comment Construct 3D image from multiple 2D images
Alternative approach: I was able to use an example by "halirutan": filenames = FileNames[]; ch[i_] := ImageData[Import[filenames[[i]]], "Bit"]; ss = Table[ch[i], {i, 1, 20}]; ListContourPlot3D[ss, Mesh -> Automatic]
