Todo:

put the output profile name as a first argument after the command, to follow STIR conventions.

Usage:

line_profiles_through_projdata [proj_data_filename] [output_profile_filename] ax_min/max view_min/max tang_min/max

ax_min/max, view_min/max, tang_min/max:

These are the minimum and maximum values of the profile for the correspondig direction (axial - angular - tangential).

Return values

output_profile_filename

Is a prefix of two text file with postfix: (a)_tang for tangential profiles. (b)_view for profiles through views. The output profile will represent the sum over all the line profiles through min/max for the directions and will produce:

Attention

Take special care of the min/max values of the direction that the profiles will be estimated. The should be the same.

This program extracts the profile of given input_projdata which should be on the center. The results is the same as if we first run ./extract_segments input_projdata.hs (by sinogram) and then run ./manip_image input_projdata.hs to extract the rows as the defaults.
