[GRASS-dev] SVM classifier and MeanShift

GRASS GIS GRASS GIS developer
1

Hi All,

I am planning to add SVM classifier to grass based on libsvm. I had a basic version of it in my private repo. I am also planning to do meanshift segmentation module.

Is there anyone working on such things currently?. Any users interested?

Mohammed,

For segmentation please get in touch with Eric Momsen who worked on i.segment recently, with great success. We were looking forward to add the mean shift option. Keep also Markus Metz in the loop - he was the mentor of the project and worked on i.segment.xl.

Also, make sure you check out the orfeo toolbox library, they have several implementations of segmentation methods.

SVM classification would also be useful. Not sure if anybody worked on it.

Best,

Pierre

Hi,

Can you tell more about segmentation which Eric Momsen worked on.

Markus Metz,
Could you comment on adding meanshift segmenation to GRASS GIS?

Please check here:
http://grasswiki.osgeo.org/wiki/GRASS_GSoC_2012_Image_Segmentation

It may be very insteresting to update i.pr to GRASS 7:
http://grasswiki.osgeo.org/wiki/GRASS_AddOns#i.pr

and integrate it into the imagery library (or closeby as related
library).

Hi Markus,

i.pr do many things and i.svm (currently developing) does SVM classification based on libsvm[0]
I hope SVM classifier will be a good thing for GRASS 7
