hello, i want to disable the blend behavior to save some time, only locate the tiles to the location PhaseCorrelation gets, but not calculate the overlap area pixel DistanceFromEdge etc,

is it possible by edit the itkTileMergeImageFilter.hxx, if yes, how can i do that?

only comment related code is not enough, it will generate a black image as i tested.

If you only want the locations, use only `TileMontage` without `TileMergeImageFilter`. That’s what example [RefineMontage](https://github.com/InsightSoftwareConsortium/ITKMontage/blob/master/examples/RefineMontage.cxx) does.
