i know LBP (local binary pattern)can be used for script identification from color images!!!but i want to identify scripts from binary image(i.e with black background and white foreground which contain texts) anyone can tell me that i can use it?!!!

From what I can tell of the reference you provided, it should be easy enough to use an existing implementation of local binary patterns to get the LLBP.
The file exchange has many implementations of local binary patterns that you can use. A simple search gave these results:
If you were to pick this entry, you could use the following approach to get the LLBP:
lbpV = efficientLBP(im,[13 1], true);
lbpH = efficientLBP(im,[1 13], true);
llbp = sqrt( lbpH.^2 + lbpV.^2 );
I haven't actually tried this out, so be mindful of that. The diagram on Fig.6 from the reference is very helpful.

Hi. I'm sorry but this format will not work. You must first generate appropriate shape filter.
Best regards, Nikolay

Hi. You can try my lineLBP implementation: http://www.mathworks.com/matlabcentral/fileexchange/50058-efficient-llbp--line-local-binary-pattern- Hope this wil do the trick. Best regards, Nikolay

extractLBPFeatures function was added to the Computer Vision System Toolbox in R2015b release.

Call the Mathworks to get a link to the toolbox which you can install. You can get a free 30 day trial if you want.
