I would like to know how to implement the basic concept of LBP operator with uniform patterns. I have implemented the basic concept of LBP operator in MATLAB. Now I am using the concept of uniform pattern.
The problem is that I am not able to understand the basic concept of LBP with uniform patterns. How exactly should it be done? Is there any documentation available which can help me?
hmm u want matlab code or just a document becoz i have done work on LBP and i have code for it also..
@ nikhil jain for the current moment i need the document only . I will need the code later to verify and compare my results
okay rakesh ..give me ur mail id I will forward you all the documents and research paper related to it.
pls explain me how uniform pattern of LBP reduces its bin to 59? can i have code of it?
It uses a mapping table, since uniform LBP are only a subset (in a manner of speaking) of all calculated LBPs. You can find more info in the papers available here, and also the Matlab code.

It enables you to map to different combinations such as uniform or rotation invariant.
If you consider the standard LBP operator LBP_8_1, you can have 2^8 distinct values that a LBP can have. Should you create a histogram of these, you would have a 256 bin histogram. Now, should you consider their binary representation and consider only the ones with at most two jumps 0→1 or 1→0, you would have a total of 58 distinct ones (see the attached figure). If you create a histogram of these and place all others into a separate bin, you have a 59 bin histogram. Check out this paper and this figure for the details.

Greetings to all researchers in this thread, i also working on LBP patterns , the discussions in this thread is very useful. i have implemented the LBP from Matlab inbuilt function, but i not understood fully the lbp concept. pls if anyone help me with MATLAB code and documentation your support wil be highly appreciated.
thanks
i got the binary line images, is it possible to extract the features from binary images using LBP. i have extracted and it is given some values is that values treated as the potential features.
thank you,
