| USAGE |
add_cpx infile1 infile2 outfile width length sign
sign: 1 (add) or -1 (subtract) infiles must be of same width and length, in cpx format. cpx format contains alternating real and imaginary pixels. Lines have width*2 pixels. |
| FUNCTION | Add or subtract cpx image files. |
| PROCESS |
Reads complex pixels from infile1 and infile2 and creates a complex pixel in outfile. From infile1 we have in_real1 and in_imag1 From infile2 we have in_real2 and in_imag2 print out_realand out_imag to outfile amp = (in_real1^2 + in_imag1^2)^.5 phi1 = arctan(in_real1, in_imag1) phi2 = arctan(in_real2, in_imag2) out_real = amp*cos(phi1 + sign*phi2) out_imag = amp*sin(phi1 + sign*phi2) |
