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

i am working on image segmentation by using growcut cellular automata method. i need the code regarding that one so please give some infiormation about my problem

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

Hi, This seems very nice piece of code, but it is giving some error...
??? Attempted to access sval(3); index out of bounds because numel(sval)=2.

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

Error in ==> test at 78
    L1 = MarkPseudoBlob( L1, bwridge, NUMTHRESH, MERGETHRESH );

i dont know why? plz help
Regards

Good work, but unable to read HD images

Hi,it's really a nice code,but it looks that a little error occurs in the 'dspimcat' function,
Is 'I2 = label2rgb(I2, 'summer', 'k', 'shuffle')' should be 'I2 = label2rgb(I1, 'summer', 'k', 'shuffle');'
and there is also a error ,it shows "CAT arguments dimensions are not consistent."

hi,i want to use this code in my experiment,but when i use the code,matlab will show "can't find mode "in ModifyWaterShed M-file.

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!
