John, is this your complete code? out_definition is not defined when used here: classifiedraster = ClassifyRaster(seg_raster, out_definition, in_additional_raster)

zoom to source resolution means, one pixel on your display corresponds to one pixel in your image. you can do this by simply right click on the image layer in Pro/ArcMap Table Of Content, and choose "Zoom To Source Resolution" we will add this to help.

Enrico, Thank you for this informative posting. Some short notes: 1. The two tools use the same code behind the scene. 2. Segment borders or color patches are different representations of same results. 3. The preview is closest to the result when you zoom to source resolution and make sure the display is large enough. So you want to fine tune you parameters in this setting. Now the long story of why: Preview is based on raster functions, which are on-the-fly processing, meaning it processes pixels currently on display (resampled to display resolution and within display extent). This is not an issue for local operations like NDVI. But it may cause a difference for regional operations like segmentation. On the other hand, actually running the tool to write out the result, will always process at source resolution. So if you zoom out/in too far away from source resolution when preview, you may see different results. Let me know if this helps, and feel free to post your updates. Thanks.

Angela, The PDF is based on common workflow mentioned in multiple papers, but we do not really have the specific article behind it.

Larry, Miha, Thank you very much for the comments. Could you provide more details on "Of course, with pan-sharpened (0.5-m) Pleiades /GeoEye, the accuracy and efficiency are still not comparable to ERDAS Objective." In your experiments, where are the error coming from? Segmentation errors or classification errors? Or something else? Could you then give us some advice on how to improve it? Your inputs are appreciated. Hua

Just a quick follow up. In ArcGIS Pro 1.3, we introduced image classification wizard and UI tools, including a re-write of training sample manager. With this tool, we hope to make the image classification workflow, including impervious surface mapping mentioned in Mark's pdf, much easier and user friendly. Thanks.
