31 Jan 2009 image segmentation using iterative watersheding plus ridge detection image segmentation for grid-pattern Author: Li CHEN

I have uploaded a paper to explain the method, hope this could be of some help to understant. Also, need several days for the website screening. 2009/2/1

I strongly suggest using MATLAB R2008a as some errors in earlier matlab version

Please help me to combine all these code in a single code

25 Feb 2014 image segmentation using iterative watersheding plus ridge detection image segmentation for grid-pattern Author: Li CHEN Ahmed, Fahad

i'm running your matlab code, when i run it on MATLAB R2011 i get the following error:

Error using .*
Integers can only be combined with integers of the same class, or scalar doubles.

Error in RemovePseudoContour (line 7)
Lmin = ordfilt2(L+bwbound.*(LABELNUM+1),1,ones(3,3)); %3-by-3 minimum filter

Error in test (line 81)
L1 = RemovePseudoContour(L1);
kindly tell me where the problem is, i'm also working on the same kind of problem, kindly get me out of it :(

Hi,
I am also seeing the error:
??? Attempted to access sval(34); index out of bounds because numel(sval)=33.

Error in ==> MarkPseudoBlob at 20
if( sval(i)<MERGETHRESH )

Error in ==> test at 77
L1 = MarkPseudoBlob( L1, bwridge, NUMTHRESH, MERGETHRESH );

I can send a copy of the image I'm using if you would like to try and reproduce the error. Thanks!
