feature extraction using Local Line Binary Patterm

i have image with size 156x156, i want block this image to 13x13 block size. can you help me to get it using LLBP??

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?

i have paper about this methode but i can make the program from the formula has been given... can you help me to make program? http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3251987/

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:

http://www.mathworks.com/matlabcentral/fileexchange/index?utf8=%E2%9C%93&term=local+binary+pattern

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.

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.

ok i'll try.thanks
