Hi Saurav,
I see you want to convert your TIFF stack to STL for shape analysis. In order to export a TIFF stack to STL you need to first create a triangulation object from the TIFF stack. You can use the "isosurface" function to first extract the faces and vertices values of the images read from .tif files. Using these as inputs, you can use the "triangulation" function to create a triangulation object. Finally, you can use the "stlwrite" function to export this triangulation object to .stl format.
Refer to the below MATLAB Answer which addresses the similar problem of exporting to .stl format: https://www.mathworks.com/support/search.html/answers/2035354-converting-matlab-isosurface-into-triangulation-object-for-stl-export.html
To know more about the above functions, refer to the following documentation:
"isosurface" : https://www.mathworks.com/help/matlab/ref/isosurface.html
"triangulation: https://www.mathworks.com/help/matlab/ref/triangulation.html
Hope this Helps!
