First off I want to say thank you offering this software because it really is impressive but I do have some recommendations based on my unique situation.
I know that you state that there are no ICE limitations but in fact I have run across one. I cannot import more than 1407 images (3.6 GB) at any one time into the program. It won't even attempt to stitch any more imagery than that and it throws an error stating it can't find an image.
I am using imagery that is collected VIA aerial photography and I am looking for some software that will be able to stitch up to 25,000 images together.
Recommendations:
1. I believe this software would be much more useful if you were able to use geo-tagged imagery. This would allow ICE to preposition and get it close to where it needs to go in the end mosaic which would result in a much faster processing time. I am currently using GEO-TIFFs.
2. It would be extremely helpful if you could use ice to Ortho-Rectify imagery within the software. I am creating mosaics using your software that are in the range of 1000 mega pixels. The problem is that I cannot export the imagery due to TIFF limitations in one file to throw into a GIS suite to do the ortho-rectification.
3. Another option that would be nice is to have a developers toolbox that can use the ICE stitching algorithms so you can customize the solution to your specific need.
Just my thoughts. I realize this is some free software right now and it is still being developed but I think you are close to having some extremely unique software.
Thanks.
