[GRASS-dev] Seeking advices for image segmentation algorithms and windows compile question

[Yang, Bo (yangb2)]

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 reported in former steps either, and I can see the file " grass71svn.bat " is located in the right place. But I still can't start the compiled GRASS. I Googled this error but can't find helpful information. Any suggestion would be greatly appreciate.

P.S. scripts in grass71svn.bat:
@echo off
