I know what local binary pattern is, and I have a demo for that, but I don't know what local line binary pattern is. Can you explain the algorithm?

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:
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.

how can I get that function since I don't have it.mine was r2015a release.just found out I don't have that function when I want to try using LBP in my project

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.
