Hi GRASS users, has anyone of you tried to use GRASS image tools (e.g. segmentation etc) to identify an object in a picture. For example I have multiple photos of fish and would like to separate the fish from its background in an automatized way. The images look like: http://fishbase.org/photos/P

Re: [GRASS-user] Image segmentation

Thanks Markus, the problem with the v.voronoi is that the polygon borders will be calculate based on point distance and not on the cost surface. Any other input? Best Giuseppe On 19 January 2017 at 02:38, Markus Metz wrote: > > > On Wed, Jan 18, 2017 at 8:16 PM, Giuseppe Amatulli < > giuseppe.

Re: [GRASS-user] Image segmentation

Thanks Pedro, yes I had already tried, but i do not get really what I want. Moreover, the delineation of watersheds is based on a predefined threshold that can be quite arbitrary give really different results. Best Giuseppe On 18 January 2017 at 14:27, Pedro Venâncio wrote: > Hi Giuseppe, > >

Hi Giuseppe, Maybe you can use r.watershed [0] to get the "basins". Best regards, Pedro Venâncio [0] https://grass.osgeo.org/grass72/manuals/r.watershed.html 2017-01-18 19:16 GMT+00:00 Giuseppe Amatulli : > Hi all, > > > > I would like to "segment" an image using a sort of Voronoi >

Hi all, I would like to "segment" an image using a sort of Voronoi

Re: [GRASS-user] Image segmentation á-la eCog nition

Orfeo indeed seems to offer the most promising features at the moment. For a more user friendly but limited option, you could also try out the OTB plugin for QGIS (http://wiki.orfeo-toolbox.org/index.php/Quantum_GIS_plugins). Cheers, Marc Am 26.03.2010 13:29, schrieb Leo Hardtke: Hello, maybe

Hello fellow GRASS users, Can anyone tell if is possible to do image segmentation, like eCognition or SPRING, in GRASS. I did some reasearch, but I couldn't find anything about it. Thank you ___ grass-user mailing list grass-user@lists.osgeo.org http:/

[GRASS-user] image segmentation in GRASS

Hello everybody, I'm new in Grass and I'm trying the image segmentation and classification with the i.smap module. This, with spot imagery 5 and 10 meters resolution. Can I see the segmented image before the classification? What do you think about the grass opportunities on image segmentation?
