/**
|
|
* SECTION: mosaicing
|
|
* @short_description: build image mosaics
|
|
* @stability: Stable
|
|
* @include: vips/vips.h
|
|
*
|
|
* These functions are useful for joining many small images together to make
|
|
* one large image. They can cope with unstable contrast and arbitrary sub-image
|
|
* layout, but will not do any geometric correction. Geometric errors should
|
|
* be removed before using these functions.
|
|
*
|
|
* The mosaicing functions can be grouped into layers:
|
|
*
|
|
* The lowest level operation is vips_merge() which
|
|
* joins two images together
|
|
* left-right or up-down with a smooth seam.
|
|
*
|
|
* Next, vips_mosaic() uses
|
|
* search functions plus the two low-level merge operations to join two images
|
|
* given just an approximate overlap as a start point.
|
|
*
|
|
* vips_mosaic1() is a first-order
|
|
* analogue of the basic mosaic functions: it takes two approximate
|
|
* tie-points and uses
|
|
* them to rotate and scale the right-hand or bottom image before starting to
|
|
* join.
|
|
*
|
|
* Finally, vips_globalbalance() can be used to remove contrast differences in
|
|
* a mosaic
|
|
* which has been assembled with these functions. It takes the mosaic apart,
|
|
* measures image contrast differences along the seams, finds a set of
|
|
* correction factors which will minimise these differences, and reassembles
|
|
* the mosaic.
|
|
* vips_remosaic() uses the
|
|
* same
|
|
* techniques, but will reassemble the image from a different set of source
|
|
* images.
|
