Re: [otb-users] Large-Scale Mean-Shift segmentation (orfeo toolbox) with TOA values not working
Thanks Jordi for answering, you are indeed right. Range radius is expressed in pixel values, so if they range in [0,1], range radius should be in that range to (and on the low end of it). Regards, Julien Le 03/08/2015 08:34, Jordi Inglada a écrit : Hi Thayse, I don't know well how the framework is implemented, but since nobody answered to your message, I will try to help here. If you start the process with the MeanShift smoothing, you have to bear in mind that the spatial radius parameter is related to the range of the input values. The default value for this parameter in the application is 15. Try to make it something like 0.1 and see what happens. Good luck.
