//This is a sample input file for backprojection program. //See input256_256.txt for another example without any comment. 16 // The first number is the number of filtered sinograms (number of angles) 29 // The second number is the number of entries in each filtered sinogram 1 // The third number is the ratio between the physical size of one sinogram entry to the physical size of one image pixel. // This number is named 'T' in the backprojection code and is a real number. // Normally, it is 1. All sinograms obtained from MATLAB should be used with T=1. // The following is the actual data of the filtered sinograms. // Obviously there are 16x29 entries here. // The correct way to arrange the data is to go over each entry in every sinogram first, then proceed to the next entry. // In other words, the very first entry below is the first entry of the first sinogram, then, the second entry below is the first entry of the second sinogram and so on. // As they are shown here, the first line below simply contains the first entries of all sinograms (so there are 16 entries in every line). // As you expect, there are 29 lines of data below. // Note, the format of the numbers in this file is the following: // -the first two numbers must be integers // -the third number (T) is either an integer or a decimal number // -the sinogram data (below) can be either integers/decimal/scientific notation (as shown here) // Basically, when you save MATLAB's variables into a file, the format you get is scientific notation. // See the function called sinoFromFile in bp_final.c, for further information. -1.8133815e-01 -1.8838553e-01 -2.2778268e-01 -2.5777989e-01 -2.6189743e-01 -2.5777989e-01
