It's my first attempt at 3D analysis. I am trying to segment a 3D CT data.
My case study is very simple: trying to segment circular objects in my data.
Do you have any suggestions on how to achieve the 3 steps:
1. First of all I would like to visualize my data in 3D
2. Then segment by value, e.g. all voxels whose value is between 800 and 1200 and visualize it
3. Than find shape properties in 3D
The way I visualize the data now is :
id = find ( D < 1200 & D > 800); [ x , y , z ] = ind2sub( id , size(D) ) ; plot3(x,y,z,'.')
Do you have suggestions for a better way?
I heard about the isosurface functions but don't know how to use it for this.
