Hello,
This is Bo Yang from the University of Cincinnati. I am working with Moritz and
Markus for the GSoC 2016 project-- Additional segmentation algorithms for
i.segment [0]. Currently, the i.segment module only provides one segmentation
algorithm: region-growing. The code of i.segment was structured in a way that
allows addition of other algorithms. I plan to add
More algorithms such as mean-shift and watershed. To prepare for it, I
searched some literatures about both algorithms below, I'd like to consult if
anyone have more recommended references.
Mean-shift:
Comaniciu, D., & Meer, P. (2002). Mean shift: a robust approach toward feature
space analysis. IEEE Transactions on Pattern Analysis and Machine Intelligence,
24(5), 1-37.
Watershed:
Shafarenko, Leila, Maria Petrou, and Josef Kittler. "Automatic watershed
segmentation of randomly textured color images." Image Processing, IEEE
Transactions on 6.11 (1997): 1530-1544.
Haris, Kostas, et al. "Hybrid image segmentation using watersheds and fast
region merging." Image Processing, IEEE Transactions on 7.12 (1998): 1684-1699.
In addition, is there anyone who use win10 OS to compile the GRASS? I have
compiled GRASS in window 10 64bit system followed the tutorial [1]. In last
step of the tutorial it mentioned:
>Usage:
>To start GRASS use the icon on the desktop or if you want to
be able to use the command line from within GRASS.
>Type in cmd console (assuming that we compiled GRASS 7.1):
>c:\osgeo4w\bin\grass71svn.bat
However, No matter I use CMD console or the OSGeo4W Shell. I got the same error
below:
'""' is not recognized as an internal or external command,
operable program or batch file.
>From the error.log there is no error during the compiling. There is no error
