I have an old aerial image that I am trying to use Orfeo Toolbox's Segmentation tool in QGIS on. The image is grey-scale. I don't know if this is a problem or not, but I am experimenting at this point, I haven't used image analysis before. It would be great if I could get this to work, I have a few images like this that I would like to use.
I found a youtube video to run a meanshift segmentation to get me started. The video left the defaults in the options window of Segmentation, so I did the same. The log of the operation follows:

To see if it was just the grey-scale image, I also used the tool with a color raster. The operation failed with the same log message. I just updated to QGIS 2.18.3 with the OTB-__ library (forgot which one it's supposed to be) in the advanced install before trying to use this tool.
