onepatchcorr(1) onepatchcorr(1) NAME onepatchcorr - Correlate a patch from two volumes at one position SYNOPSIS onepatchcorr xsize ysize zsize xcen ycen zcen filea fileb out- put_file DESCRIPTION onepatchcorr will determine the 3-D displacement between a single sub- set or patch extracted from two image volumes in filea and fileb. It extracts the patch from each of the two volumes using tapervoledge. It then uses clip to do 3-D cross-correlation between the patches and determines the displacement of the patch in fileb relative to the patch in filea. It writes a single line to the output file giving the dis- placement between the two files in X, Y, and Z. ARGUMENTS The size of the patch in X, Y, and Z is set by the arguments xsize, ysize, and zsize. The location of the center of the patch is given by the index coordi- nates xcen, ycen, and zcen.
