The distortion is such that the landmarks of the source are mapped to those of the target. Most of the time, the automatic algorithm requires no user input because it is robust enough that the default initial conditions are sufficiently accurate.Īfter completion of the registration process, the plugin uses the final position of the source and target landmarks to create a warped image that has the size of the target and that contains a distorted version of the source. In the manual mode, this automatic refinement procedure is disengaged. In the automatic and batch modes, the landmarks of the source image are then automatically refined to better match those of the target image. In all three cases, the user is given the opportunity to interactively specify some landmarks, which establishes the initial correspondence between the images. Three alignment modes are available: manual, automatic, and batch. The purpose of this plugin is to register-in other words, to align or to match-two images, one of them being called the source image and the other the target image. Before (left) and after (right) having applied the alignment procedure to an eye fundus.
