I'm attempting to create a seamless blend between a high-res and a low-res 3 band raster (aerial photos) and then export to tiff so the seamless image can be used in another application.
Setting up the blend is no problem....
- Add rasters to mosaic
- Build seamlines
- Set mosaic properties to 'Blend'
However the process of outputting to a tiff using MosaicToNewRaster takes a very long time - I have tested with a blend size of 50 pixels and it takes an hour; but the blend size I'd like, to get the effect I want, will be more like 200-300 pixels - so I'm testing this and I'm waiting and waiting and waiting......4 hours and counting.....
I'm doing this with Python because it's a process I might need to repeat many times so this long processing time is not good.
Can anyone suggest any ways I may get quicker results?
(I have a powerful machine with a good graphics card)
