vapoly − fit polynomial from tracked aorta centerline points
SYNOPSISvapoly if=<chestmap> iv=<centerpoints> of=<visualization> st=<startindex> en=<endindex> scale=<xres,yres,zres> p=<order> -w -v
DESCRIPTIONvapoly takes in a GFLOAT vector file (iv) and fits a p-order polynomial to a segment of the vector file, starting from st index to en index of the vector. It is the same as vfitpoly except for different input structures.
CONSTRAINTInput file if is a chest map image. Input file iv is the output GFLOAT vector file with coordinnates of center points (output from vveccom). scale is the x,y,z resolutions of the image. st and en are the index numbers of segment for polynomial fitting (output from vveccom). p is the order of polynomial function. When -w is specified, the ’xfit’,’yfit’ and ’zfit’ coefficients are printed.
