I know that this is a long shot...

Is there any chance of having the sort of features that would be needed to manually tidy up the results of segmentations of 3D images (from CT scans). The sort of things I'm thinking about are.

1. The ability to overlay two voxel images in the same editing space (e.g. one for the original image and one for the segmentation with added alpha channels).

2. The ability to draw arbitrary sheets of voxels by e.g. selecting 3-4 voxels as the corners of the sheet.

3. In terms of image format one would need to handle images with e.g. float32 and int32 greyscale voxel values. Import and export of raw binary images would be nice.

Just wondering. Some of the proprietary 3D analysis suites have these editing features but as far as I know the FOSS solutions for 3D image processing don't include any editing functionality.

3D Slicer (http://www.slicer.org/) has most (if not all) of that, if I understood your questions. I have struggled with the learning curve, though. YouTube helps sometimes.

I haven't found the functionality to change the value of ability voxels in Slicer yet -- in particular for sheets with corners supplied by the user. Is it there and I'm just being dumb?
