Method

VipsImagematch

Declaration [src] 

int
vips_match (
  VipsImage* ref,
  VipsImage* sec,
  VipsImage** out,
  int xr1,
  int yr1,
  int xs1,
  int ys1,
  int xr2,
  int yr2,
  int xs2,
  int ys2,
  ...
)

Description [src]

Optional arguments:

  • search: search to improve tie-points
  • hwindow: half window size
  • harea: half search size
  • interpolate: interpolate pixels with this

Scale, rotate and translate sec so that the tie-points line up.

If search is TRUE, before performing the transformation, the tie-points are improved by searching an area of sec of size harea for a match of size hwindow to ref.

This function will only work well for small rotates and scales.

This method is not directly available to language bindings.
