I want to use lbp as a feature extraction technique but the features that i extract should only be translation and scale invariant.it should not be rotation invariant

lbp features are not invariant to any of scale,translation or rotation.

if you use histograms of (grid) patches, that will make it invariant against scale.

How to implement it? Do u have a link or tutorial. And isn't lbp translation invariant

"And isn't lbp translation invariant" -- why ?

if you use histograms of (grid) patches, it will be "robust" against some translation/rotation.

http://docs.opencv.org/ref/master/da/..., see bottom, lbph chapter

Well it depends on how you look at the feature itself. Afaik the LBP feature is locally rotationally invariant right?
