case2.1: Generate Burn Data and Print Raster Images with Fiducial Polygon

 

  

Input Data Options special purpose data requiring pre-processing (0) tomographic data (1) segmented data (2) burn data (3) medial axis data (4) throat data (5) Enter choice: 2

Data Processing Options burn image (1) burn and compute LKC medial axis/surface (2) disconnected volume distribution (3) moment of inertia of disconnected components (4) plot image (5) convert data to/from ascii format (6) 2-point covariance function (7) tomographic/segmented data covariance comparison (8) compress data in z direction (9) count voxels in spherical/cylindrical shells (10) set fiducial polygon exterior to grain phase (11) remove isolated voxel clusters from data (12) Enter choice: 1

Files assumed to be labelled basename.ext, basename is limited to 255 characters maximum, ext is a numerical designator lying between 000 and 999 It is assumed that the files have consecutively numbered extensions ie. 000 -> 056, or 021 -> 049

Enter basename for segmented files: ../../Examples/data/berea/berea_bit Are files compressed? [y,n]: y

Enter first and last slice of data to use: 1 5 Isolated clusters of grain and/or pore voxels up to a specifed size can be assumed to be misidentified and converted to the opposite material type. Convert isolated grain clusters? (y,n): n Convert isolated pore clusters? (y,n): n

The material/void boundary can be lightly smoothed. Available options are 0) no conversion or convert those boundary voxels having 1) exactly one neighbor of the same type 2) less than a majority of neighbors of the same type Enter choice (0(dflt),1,2): 0

Input data can be inverted to compute burn/medial axis of grain space rather than void space. Invert data (y/n): n

Exclude the first or last slices to compensate for lack of information beyond the end slices? [(n)one, (f)irst, (l)ast, (b)oth]: n

Enter basename for burned files: burn Are files to be compressed? [y,n]: y

Fiducial polygon generation methods NONE (N) MANUAL (M) AUTOMATIC (A) Enter method: M

MANUAL fiducial boundary calculation

The bounding curve for each fiducial polygon should be convex in the sense that at most 2 points on the bounding curve have the same y coordinate. Enter number of polygons: 1

Are the coordinates of the fiducial polygon(s) stored in a file: y Filename of fiducial polygon 1: ../../Examples/data/polygon.400

Would you like a raster format printout displaying the fit of the fiducial polygon (y,n(dflt)): y

For how many of the slices do you wish raster file printout: 1 Enter slice numbers, one per line at the prompt. : 3
