A LBP is called uniform if the binary pattern contains at most two 0-1 or 1-0 transitions. For example, 00010000 (two transitions) is a uniform pattern, 01010100 (six transitions) is not. For the computation of
This chapter presents a Feature Local Binary Patterns (FLBP) method that encodes both local and feature information, where the feature pixels may be broadly defined by, for example, the edge pixels, the intensity peaks or valleys in an image, or new feature information derived from the local ...
Second example : compute MBLBP and CS-MBLBP Features on image I for scale = {1,2} Third example : Display best MBLBP Features from Gentleboosting & Adaboosting Fourth example : compute MBLBP Features + Adaboosting with T weaklearners (Decision Stump) Fifth example :...

15 ×15 blocks. From this example we can see what influence parameter s would make. For a small scale, local, micro patterns of a face structure is well rep- resented, which may beneficial for discriminating local details of faces. On the ...

The most common example of this category is SIFT [12] which is rotated around the dominant patch orientation. Varma and Zisserman [23] have applied a similar approach to texture classification using filter banks. The texture descriptor proposed in this paper is based on the Local Binary Pattern...
On the other hand, microstructure simply using pixel neighborhoods as small as 3×3 pixels for local pattern representation has been proven to be possibly powerful for discriminating texture information, where the most popular one is a local binary pattern (LBP). LBP [12–14] characterizes each ...
